Toto Wolff believes Mercedes need to make "radical" changes after suffering "one of the worst days in racing" at the season-opening Bahrain Grand Prix.

Red Bull dominated in Sakhir on Sunday, Max Verstappen leading a one-two ahead of Sergio Perez.

Lewis Hamilton could only finish fifth and his Silver Arrows team-mate George Russell was seventh in the first race of 2023.

Seven-time F1 world champion Hamilton crossed the line 50.977 seconds after Verstappen, who is a strong favourite to clinch a third consecutive title.

Mercedes team principal Wolff knows his team are unable to challenge Red Bull and must go back to the drawing board.

"One of the worst days in racing," Wolff told Sky Sports F1.

"Really not good at all, we were just lacking pace front, right, and centre.

"Red Bull is just on a different planet. That is what hurts because they are so far ahead, it reminds me of our best years because we just put a second on everybody else.

"That is the benchmark and we have to do one step after the other to come back and we can do that. We can, absolutely we can.

"I think it needs to be much more radical in the steps than hope for a three-tenths upgrade."

The second race of the season will be staged in Saudi Arabia on March 19.

George Russell says Red Bull have got this year's Formula One championship "sewn up" and declared "they should win every single this year" after dominating the season opener in Bahrain.

Red Bull's Max Verstappen and Sergio Perez claimed a comfortable one-two finish at the Bahrain Grand Prix having both started at the front of the grid.

The reigning world champion won by 11.987 seconds from his Red Bull team-mate, who was almost 40 seconds ahead of Aston Martin's Fernando Alonso who rounded out the podium.

Mercedes team principal Toto Wolff said Red Bull were on a "different planet" after the race and felt his team would need to completely abandon its own cap concept.

Russell, who finished down in seventh, reiterated that sentiment, pointing to Red Bull's probable dominance in 2023.

"Red Bull have got this championship sewn up," Russell said. "I don't think anyone will be fighting with them this year. They should win every single race this year, is my bet.

"They've got it easy at the moment. They can do what they like. They might not be on pole all the time because we know Ferrari are very competitive in qualifying but when it comes to race pace they're in a very strong position."

Red Bull team principal Christian Horner downplayed Russell's comments, insisting it was far too early to be talking like that.

"Twenty-three races is a marathon," Horner said. "It's about being consistent over the campaign.

"Today was a great start. We full expect our rivals to come back hard in the future races."

Lewis Hamilton called for Mercedes to implement upgrades as soon as possible after a disappointing opening race at the Bahrain Grand Prix.

The seven-time world champion was well off the pace of the Red Bulls, who secured a one-two finish, and came fourth after losing his battle with former team-mate Fernando Alonso.

Aston Martin's show of strength is a particularly sore point for Mercedes, who supply their engine, gearbox and rear suspension, and fans may fear another tough season is on the cards for the team.

A disappointing campaign last term saw Mercedes respond to provide some competitiveness in the final rounds but Hamilton is keen for a much swifter reply this year.

"I thought the team did a great job in terms of pit stops and just unfortunately the car is not there at the moment," he told Sky Sports F1.

"We are just lacking downforce and we have got to work really hard to add that ASAP.

"Anything from in the wind tunnel, we need it tomorrow. We have really got to push massively to try and close that gap."

Team principal Toto Wolff is equally keen for developmental upgrades, but he feels a more radical approach is required.

The fact Aston Martin have impressed has provided some optimism, though, if the team can pinpoint where their success stems from.

"Red Bull is just on a different planet. That is what hurts because they are so far head, it reminds me of our best years because we just put a second on everybody else," he said.

"That is the benchmark and we have to do one step after the other to come back and we can do that. We can, absolutely we can.

"I think it needs to be much more radical in the steps than hope for a three-tenths upgrade.

"They [Aston Martin] deserve what they have done, they did a good job. The good news for us is there is a lot of Mercedes in there.  To pinpoint it, that would be helpful in the recovery."

Charles Leclerc believes Red Bull are on "another planet" to their Formula One rivals after they dominated the season-opening Bahrain Grand Prix.

Max Verstappen's title defence got off to a comfortable start with a victory on Sunday, with his team-mate Sergio Perez second and Aston Martin's Fernando Alonso in third.

Leclerc looked on course for a podium finish for Ferrari, but an engine failure led to his retirement.

The issue came despite Ferrari changing a component ahead of the race, one of only two permitted alterations allowed over the course of the season, which could lead to further pain for the Scuderia in future races.

While the cause of the problem was unknown to Leclerc, he made it clear the team must secure as many points as possible to keep Red Bull in sight.

"I have no idea what happened to the car when I lost the power, the only thing I know is that I did, I don't know for what reason," he told Sky Sports F1.

"I don't know if it is related to the change we had this morning, so I don't want to comment on that, but it is a shame.

"We expected to be on the back foot this weekend, especially in the race to Red Bull. That team is on another planet right now.

"But that's what exactly why most weekends we need to make sure we bring maximum points possible home and we didn't manage to do so."

Max Verstappen was delighted to break his Bahrain Grand Prix hoodoo, but Red Bull team-mate Sergio Perez is promising a tight Formula One title race in 2023.

The reigning world champion picked up his first career victory at the Bahrain International Circuit to kick off the new season where he left off last term.

Verstappen led a one-two ahead of teammate Perez, while Fernando Alonso came third on his Aston Martin debut.

Having failed to win on any of his previous visits to Bahrain with the team, the Dutchman acknowledged he was gratified to finally claim a win at the circuit.

"I was very happy to finally win here in Bahrain," he said in his post-race interview. "It was a very good first stint. From there, it was about looking after the tyres.

"[There are] just little things we want to fine-tune. I think we have a good race package. I think it will depend race-to-race, [but] we can definitely fight with this."

Perez, who was aided in securing second by the late retirement of Ferrari's Charles Leclerc to an engine issue, feels he can press his team-mate this year though.

After finishing third in the standings last term, the Mexican is looking to ensure he can stay on the heels of the Dutchman as the latter eyes a third consecutive crown.

"We worked really hard over the winter, so it is nice to see all the boys enjoying the first race," he added. "It was important today to get both cars to the end.

"Finishing second was the maximum I could do today [with my start]. It is a long season. I think I am getting closer every single session and I will give my best."

Alonso, who departed Alpine for Aston Martin during the off-season, nabbed his first podium finish since he came third at the 2021 Qatar Grand Prix.

For the Spaniard, the oldest driver in the field at 41, it marked a vindication of his decision to make the move as he continues to defy expectations.

"[It is] amazing for the team, [it] was [a] great weekend," he added. "Finishing on the podium in the first race of the year, it is just amazing.

"What Aston Martin did over the winter to have the second-best car on race one, it's unreal."

Max Verstappen started the defence of his Formula One title with a comfortable victory at the Bahrain Grand Prix.

The two-time world champion was in front from the start and never truly came under threat, leading a Red Bull one-two ahead of Sergio Perez to secure his team's first opening-weekend victory since 2011.

With Charles Leclerc forced into a retirement due to an engine issue, Red Bull's closest challenger was Fernando Alonso, who worked his way through the field for a podium finish.

But a rejuvenated Aston Martin were no match for a dominant Verstappen and Red Bull in what proved to be a comfortable race for the defending champions.

Leclerc, who had a power unit change before the start, leapfrogged Perez to take second place at the start but could not stay ahead of the Mexican, who regained his grid position after the first round of pit stops on lap 26.

Mercedes' fight with Aston Martin was the battle to watch, Lewis Hamilton completing an undercut on Alonso before a stellar move on lap 38 saw the Spaniard move ahead again.

Engine problems for Leclerc led to his retirement three laps later, opening the door for Alonso to battle Carlos Sainz for a podium spot after the virtual safety car was deployed.

Alonso was able to catch his compatriot on lap 46 to clinch third spot in his first race for Aston Martin, though there was no challenge for Red Bull as they eased to only their second ever win in the first race of the year.

Ferrari frustration

Having had to retire from the lead twice in the 2022 season due to engine issues, Leclerc would have hoped those problems were a thing of the past heading into Ferrari's 2023 campaign.

Never appearing to have the pace to put the Red Bull duo under threat, calamity struck with another forced retirement in a nightmare start to the season.

Ocon's Alpine agony

Esteban Ocon's season did not get off to a good start, with the Frenchman given three time penalties over the course of the race.

An initial five-second penalty came for incorrect grid position, with a 10-second penalty following for failing to serve that correctly and another five-second penalty issued for speeding in the pit lane before the Alpine was eventually retired.

Charles Leclerc has taken a new power unit component ahead of the Formula One season opener in Bahrain.

The Ferrari driver, who starts third on the grid behind the Red Bulls of Max Verstappen and Sergio Perez, has a new energy store (ES) on his car.

No penalty will be issued for the Bahrain Grand Prix, though it leaves Ferrari in a challenging position for the remainder of the season as only two such changes are allowed over the course of the campaign.

The F1 season in 2023 will see a record-breaking 23 races on the calendar, Las Vegas having been added to the schedule.

Leclerc looked to be Verstappen's strongest rival last season, winning two of the opening three races, but reliability issues and strategy errors derailed his charge as he finished 146 points behind the Dutchman.

Changes were made at Ferrari ahead of the new season, Frederic Vasseur replacing Mattias Binotto as team principal.

Toto Wolff conceded Mercedes must change their car design in order to return to the top of Formula One.

Mercedes endured a dismal 2022 season, with Lewis Hamilton suffering the first winless campaign of his F1 career.

Much of their struggles were put down to issues with the car, but Mercedes stuck with their unique "zero pod" design for the 2023 season, despite the success of Red Bull's "side pod" model.

Yet after a disappointing qualification session that saw George Russell place in sixth and Hamilton in seventh for Sunday's season-opening Bahrain Grand Prix, Wolff confirmed changes will have to be made.

He said: "I don't think this package is going to be competitive, eventually.

"We gave it our best go also over the [off-season] and now we just need to all regroup, sit down with the engineers who are totally not dogmatic about anything and decide what is the development direction we want to pursue in order to be competitive to win races.

"It's not only like last year that you're scoring podiums and eventually you get there.

"I'm sure we can win races this season but it's really the mid-and long-term that we need to look at which decisions you need to take."

Wolff believes Mercedes "gave it our best shot" but ultimately the team must accept their model has not worked.

"We hit our targets. That's why we gave it our best shot," he continued. "The moment comes and the stopwatch comes out and that showed us that it's simply not good enough.

"We haven't got enough downforce and we need to find solutions to fix that."

Two-time reigning world champion Max Verstappen claimed pole position in Saturday's qualification, with team-mate Sergio Perez completing a front-row lockout for Red Bull.

Ferrari duo Charles Leclerc and Carlos Sainz will start in third and fourth respectively, while Aston Martin's Fernando Alonso occupies fifth on the grid ahead of Russell and Hamilton.

After a close-season of significant change, the starting grid for the Bahrain Grand Prix has a familiar look with Max Verstappen starting the new campaign on pole ahead of Red Bull team-mate Sergio Perez.

Pre-season testing at Sakhir had suggested the reigning world champion and his team would maintain their superiority to start the 2023 campaign, and further evidence to back up that point was provided in Q3.

Ferrari topped the timesheets in the opening two qualifying sessions, but it was Verstappen who reassumed command in the top-10 shoot-out with a time of one minute and 29.708 seconds.

Ominously for the two Ferraris on the second row, Charles Leclerc in third and Carlos Sainz in fourth, Verstappen's lap came following some significant struggles with the balance of the car, issues Red Bull fixed in time for the Dutchman to set the pace and put himself in position to dominate on race day.

Verstappen told the post-qualifying press conference: "I'm particularly happy because my whole weekend up until qualifying was very difficult.

"I couldn't really find the comfortable balance I had in testing and I was just struggling a lot to just get the car together, really. I went into Q1 and everything already felt a bit better, but it was still not, let's say, perfect. So yeah, I'm very happy then in Q3 that we could put these laps in.

"I still think it's not perfect, but in a better direction. So, for sure, for the next race we will have to analyse a bit why from the test to the race weekend it's so different for us, and also for me driving wise.

"But nevertheless, we are sitting here with two cars. So coming off last year I think this is again a very strong start for us. So yeah, very happy with that.

"Luckily in qualifying that's probably the best balance I've had throughout the weekend so far."

Asked about the race, he added: "That should normally be our stronger point than the one-lap pace. So hopefully we can show that again tomorrow."

Verstappen, though, knows he can take little for granted, acknowledging the field is closer than it was last season.

In Q1, first-placed Sainz and Nyck De Vries in 19th were separated by just over a second and, in addition to looking over his shoulder at the Scuderia, Verstappen may also have to concern himself with the threat of Aston Martin, who saw Fernando Alonso qualify fifth in his debut for the team ahead of the two Mercedes.

"They are all very close to us," Verstappen said when asked about to name his closest challengers. "Of course, we have shown really good race pace but we still need to show that tomorrow, and a lot of things can happen also during a race, which sometimes is not in your control.

"So yeah, we just, of course, need to focus on ourselves and try to do the best we can. And hopefully no crazy things will happen."

But Leclerc did not express much hope of Ferrari overhauling Red Bull in the race.

"I think we are only happy if we win," said Leclerc. "But again, realistically, they seem to be very, very quick.

"So I think in those weekends where we are a little bit underneath, that's exactly those weekend that we need to maximise and, and try to get what we can in terms of points.

"So yeah, if a win is possible tomorrow, I will go for it. If not, we'll try and get the maximum points."

Mercedes boss Toto Wolff will do anything it takes to see Lewis Hamilton win his record-breaking eighth world title.

Wolff would go as far as pushing Hamilton "around the track" if it meant the 38-year-old clinching his eighth Formula One triumph.

That would see Hamilton surpass Michael Schumacher, with whom he shares the record of seven championships.

Hamilton and Mercedes endured a difficult campaign last year, however, as he suffered the first winless season of his F1 career.

Mercedes' 2023 season did not off to the greatest start on Saturday, with Hamilton qualifying seventh and his team-mate George Russell in sixth for Sunday's Bahrain Grand Prix.

But Wolff is sure they will have more success than in 2022, and he will go to extremes to ensure Hamilton gets his eighth title at some stage.

"We're going to get his eighth. He has, compared to [Aston Martin's Fernando] Alonso, another four years in him as a minimum so we just need to get it done," Wolff told Sky Sports.

"Even if I have to push him around the track to win the eighth I am going to do everything that is needed."

Hamilton himself was confident he could close the gap on pole-sitter Max Verstappen in Sunday's season opener, and Wolff echoed the sentiment even if he conceded it was an ultimately disappointing qualifying session.

He added: "The gap is not ridiculous considering we only ran one tyre at the end but it is not where we want to be. 

"We are continuing to develop the concept and thinking we could land it and fight for pole position and that wasn't the case today. 

"That is the gap and this is what we need to find, or more, to win. 

"We could have potentially overtaken Alonso [in fifth] with both cars but this is where we are. We are super critical with ourselves and what we need to achieve.

"We are looking at everything to get it right with the concept, should we have reacted earlier, all of that.

"Everybody in the engineering team thinks like that and we just need to get our act together."

It was a similar story for Russell, who said: "Our goal was to make sure we've got a car we can build upon and that there aren't any significant problems.

"We spent probably three-quarters of last year problem solving and now I feel we've got a car which is nice to drive.

"It generally feels like a good car, and now we can focus on adding downforce and performance which is what the team have done for so long. 

"There are definitely signs to be positive, but we've got a lot to improve."

Formula One world champion Max Verstappen surprised himself by claiming pole position in qualifying for the Bahrain Grand Prix.

Verstappen, on the hunt for a third straight world title, will start at the front of the grid in Sunday's season-opening race after recording a quickest lap of 1:29:708 on Saturday.

Red Bull team-mate Sergio Perez qualified in second to complete the front row, with the Ferraris of Charles Leclerc and Carlos Sainz behind them on the second row.

Seven-time world champion Lewis Hamilton had to settle for seventh behind Mercedes team-mate George Russell, with Fernando Alonso wedged in fifth.

Ferrari had topped the opening two qualifying sessions but with Verstappen coming good in Q3, they elected against heading out again, instead choosing to conserve their tyres.

"It has been a bit of a tough start to the weekend yesterday and today not really finding my rhythm, but luckily in qualifying we managed to put the best pieces together," Verstappen said.

"I am very happy to be on pole. For the whole team coming off last year and again having such a strong car with Checo up there as well. It is amazing and I am looking forward to tomorrow. 

"The changes slowed down the car a bit but we are still going faster, which is great to see. Throughout the year, you will see everyone increasing their performance again a lot and that is the beautiful thing about Formula One.

"I was actually positively surprised to be on pole after the struggles I had in practice. Normally our race car is better, so let's see."

Despite having plenty of work to do to compete for a podium finish, Hamilton was in a buoyant mood.

"We went in with a really open mind," he told Sky Sports. "I woke up thinking we were going to be a lot further behind, and so the fact we're even getting into Q3 was great.

"We made a step forward today and the car was feeling much more alive this morning, and all of a sudden we were in a different place to where we were the day before. But then we got to qualifying and for me the car just didn't feel alive, it felt kind of average.

"It's not an impossible mountain to climb, so that's a positive, and I know everyone back at the factory has been working so hard. We can definitely close the gap, we've just got really focus and push like never before."

Leclerc, meanwhile, was happy with Ferrari's strategy despite believing he had the chance to fight for pole.

"There wasn't any issue. I think we were in the fight for pole, which was a good surprise to be honest because I did not expect that after testing and after free practices that were a little bit difficult," Leclerc said.

"We managed to find that pace for the qualifying pace, which was great. However, we need to keep in our mind that on the race runs, we seemed to be a little bit on the back foot compared to Red Bull.

"I think that we're in a better place starting third with new tyres than starting first with older. I don't know if I would have been in pole or not but it would have been close."

PROVISIONAL CLASSIFICATION

1. Max Verstappen (Red Bull)
2. Sergio Perez (Red Bull)
3. Charles Leclerc (Ferrari)
4. Carlos Sainz (Ferrari)
5. Fernando Alonso (Aston Martin)
6. George Russell (Mercedes)
7. Lewis Hamilton (Mercedes)
8. Lance Stroll (Aston Martin)
9. Esteban Ocon (Alpine)
10. Nico Hulkenberg (Haas)

Fernando Alonso provided an unlikely threat to Max Verstappen and Red Bull in practice ahead of the season-opening Bahrain Grand Prix.

Verstappen and Red Bull will be expected to take the Formula One title again this year after dominating in 2022.

But Verstappen topped the charts in neither of the first two sessions of the week on Friday.

Team-mate Sergio Perez was fastest in FP1, yet Aston Martin's Alonso was in second, ahead of third-placed Verstappen.

In FP2, F1 great Alonso then went one better with the fastest time. Verstappen was again one place back, in second, with Perez third.

Red Bull could at least be encouraged by the lack of a credible challenge from their long-standing rivals.

Charles Leclerc was fifth and then fourth for Ferrari, and the two Mercedes cars were further back still.

Lewis Hamilton was made to work hard for a pair of top-10 finishes in 10th and eighth, while George Russell settled for 11th in FP1 before falling to 13th in FP2.

A new Formula One season is upon us and the 2023 campaign will be the longest in the history of the elite motorsport class.

The number of races is rising to 23, with Las Vegas joining the show, though drama will not be limited to the track.

Two seasons ago, the controversial conclusion to the campaign in Abu Dhabi was a dominant story, while last year saw Red Bull's budget cap breach and an Oscar Piastri fight between Alpine and McLaren, as well as frustrations with governing body the FIA, notably over the drivers' freedom of expression.

Get set for sporting theatre to unfold over the course of the season ahead, though the biggest talking point centres around whether anyone can dethrone Red Bull.

Red Bull gives you wins

Max Verstappen finished at the front in 15 of 22 races last season, setting a record for the most triumphs in a single campaign, and he has won over half of the events in the past two years (25 wins from 44 races).

While pre-season testing never offers a full indication of what lies ahead, Red Bull's strength was still evident and the consensus is that the defending champions will begin the campaign with an advantage over their rivals.

If that gap cannot be reduced, the biggest threat to a third consecutive crown for Verstappen may come from team-mate Carlos Perez. Should that happen, tempers may flare as they did in Sao Paulo in November when Verstappen refused a team order to allow the Mexican through.

One aspect that may provide hope to Red Bull's rivals is the punishment issued for the budget cap breach, which included a 10 per cent reduction in aerodynamic testing allowance for 12 months. While it came too late to have a major implication on the overall develop of this year's car, it could restrict the team's ability to fix any issues that arise.

Ferrari's fight to the front

A season that offered so much promise for Ferrari last term ultimately fell away through mistakes in race strategy and engine failures, the latter of which resulted in the team having to run in a low-power mode to avoid further woes.

Charles Leclerc certainly has the ability to go head to head with perennial rival Verstappen, who he has raced since his junior days, while Carlos Sainz got his long-awaited maiden F1 win at Silverstone last year.

The appointment of Fred Vasseur as team principal, replacing Mattia Binotto, hands the Scuderia an experienced head on the pit wall and may result in fewer questionable calls in race strategy.

Ferrari are confident they can mount a challenge this season and, even though Leclerc has conceded Red Bull may start with an advantage, he believes the Prancing Horse can respond.

"The target is still [to win the title]. Even if we are starting a bit of the back foot compared to them in terms of performance, I'm sure we can come back," Leclerc told Sky Sports.

Mercedes on a mission

Any hopes of a Mercedes revival in 2023 appear to have stalled already, with testing performances suggesting the team may have to look over their shoulders at those chasing from behind rather than competing at the top.

Mercedes' design continues to divide opinion, with a zero-pod approach being vastly different to their rivals and leading to questions about whether they have stuck to their guns out of pride rather than sporting merit.

With Lewis Hamilton behind the wheel, there is always a chance and the Briton will be determined to come back and add to his record 103 race wins having failed to secure a victory last season – the first campaign in his career when he has not registered a win.

The seven-time world champion was outperformed by team-mate George Russell last season, however. Russell secured a maiden race win in the penultimate race and offered consistency throughout the campaign.

Best of the rest

The biggest surprise of the testing weekend in Bahrain was the pace shown by Aston Martin who, with the addition of Fernando Alonso, have a driver who could mount a serious threat to the bigger guns on the grid.

Though a third world title for the Spaniard may be a stretch, regular podiums and dethroning one of the big three in the constructors' championship is certainly an achievable goal.

At Alpine, great care will be taken to ensure French compatriots Pierre Gasly and Esteban Ocon do not find themselves butting heads, with a frosty relationship over the years, while McLaren have already admitted they missed their development targets and start on the back foot as a result.

Andreas Seidl, now at the helm of Alfa Romeo-Sauber, enters with high expectations ahead of the team's transition into Audi in 2026, while AlphaTauri's long-term future continues to be questioned despite assurances Red Bull will not sell their second-string team.

Expect the season to also see further rumblings regarding new additions to the grid, with Porsche and Andretti among those pushing to join.

As ever, there is plenty to watch out for in F1 and from the first corner to the last there are likely to be surprises along the way.

Charles Leclerc is confident Ferrari can compete with Red Bull for both titles in the new Formula One season.

Ferrari failed to capitalise on their strengths last year and compete with Max Verstappen, who waltzed to a second consecutive championship title.

Early signs ahead of the 2023 season suggest Red Bull remain ahead of their rivals, with Leclerc admitting that is a perception he holds.

However, he believes Ferrari can mount a threat over the course of the season due to the developments from last year.

"From what I can see, it seems Red Bull is a bit ahead. But it's a long season, our goal is still to win the championship," he told Sky Sports.

"I am confident. We have great guys in Maranello, I think we have shown it with the big step forward from 2021 to 2022.

"There were too many mistakes in 2022, we know that, but we've been very honest with ourselves in order to get better for this season.

"The target is still [to win the title]. Even if we are starting a bit of the back foot compared to them in terms of performance, I'm sure we can come back."

Leclerc's assessment that Red Bull begin the campaign ahead of their rivals is shared by Mercedes' George Russell, who expects them to dominate the opening weekend in Bahrain.

"It probably wasn't the smoothest three days we could have hoped for at testing. But the learning we found is going to put us in better stead for this weekend," he said in Thursday's press conference.

"I think it’s definitely fair to say Red Bull are in a league of their own this weekend. But it'll probably be a nice fight for second between Ferrari and Aston Martin."

Lewis Hamilton rebuffed suggestions the 2023 season will be his final year in Formula One and is adamant he will be at Mercedes next season.

The seven-time champion is in the final year of his contract with the team, who are expected to be off the pace of rivals Red Bull in the hunt for the championship.

Speculation that Hamilton will walk away from the sport has persisted ever since a controversial conclusion to the 2021 season, when Max Verstappen pipped him to the title in Abu Dhabi.

Hamilton returned to the grid for 2022, although Mercedes struggled and lost their constructors' championship crown to Red Bull, and is set for a 17th season in F1 in 2023.

The Brit is not set for a swansong, as he hit back at claims from former F1 drivers Jenson Button and Damon Hill that he will retire following the campaign.

"It is ultimately people creating rumours without facts, and it is never helpful. You would have thought that they [Hill and Button] would both know me by now," he told reporters ahead of the opening race of the season in Bahrain.

"I have been with Mercedes since I was 13, and last year we had a difficult year, but I am still here, and whether or not we have a difficult year this year, I will still be here.

"I am a fighter, and we fight as a team. I love the challenge of finding solutions and I still believe I am able to put the car in places that perhaps others are not able to. I love that challenge.

"Of course, I wish we started the season with a great car, but it is the journey that really counts."

Negotiations over a new contract for Hamilton are continuing, with the 38-year-old confident an agreement will be reached.

"There is no hold-up with our contract. I have always been very, very relaxed and I don't feel like I have to get it done right this second. I am in a very fortunate position," he added.

"It will get done when we are ready. I have a great relationship with Toto and with Mercedes and we fully support each other.

"I am really excited about the future together and really proud of the work we are doing, on and off the track and the potential of new things that we can do moving forward.

"We will get there, unless something catastrophic happens between me and Toto [team principal Wolff] and we get in the [boxing] ring, but other than that we are good."
