How does Formula One go about following up the epic 2021 season?

Well, until that stunning campaign stole the show, this year was long seen as the one to look forward to with the introduction of new regulations to encourage competitive racing right down the grid.

Lewis Hamilton might have expected a genuine challenge in 2022; instead, in the form of Max Verstappen, it arrived 12 months early.

Excitement for the coming campaign is therefore at an all-time high, with pre-season testing adding to the theory fans should expect the unexpected.

Forecasting the year ahead is tricky, but Stats Perform seeks to identify the key narratives to follow this season ahead of Sunday's 2022 opener in Bahrain.

Max vs Lewis again

For now at least, Verstappen and Hamilton will expect to be the title frontrunners, which should mean another classic campaign.

Verstappen had never even led the standings until winning last year's Monaco Grand Prix, the first of five consecutive Red Bull wins – including four for the Dutchman.

That sequence ended at Silverstone, where contact with Hamilton sent Verstappen into the wall and set the tone for the rest of a frantic season, in which the pair repeatedly went at one another, crashing at Monza.

A titanic back-and-forth deserved a better ending than to be decided by a contentious call from race director Michael Masi in Abu Dhabi.

Now, defending champion Verstappen can attempt to prove he is better than Hamilton regardless of that decision, while the Mercedes man seeks to show his class once again as he pursues a record eighth title.

The midfield challenge

The game-changing 2022 regulations sought to enforce "closer racing", meaning both Verstappen and Hamilton could come under threat rather than simply blowing away the competition.

Early signs are encouraging on that front, with the two title rivals name-checking Ferrari's superb pre-season showing in the past week.

A resurgent Scuderia represent an obvious danger to those two, but so too do McLaren, Ferrari's midfield neighbours in recent seasons.

Lando Norris had four podiums last season before tailing off to finish sixth in the drivers' championship – still two places ahead of team-mate Daniel Ricciardo, who endured a tough first year with the team despite a famous win at Monza.

Having been aided by changes to the car for 2022, it is up to Ferrari and McLaren to close the gap considerably to Red Bull and Mercedes.

George a genuine threat?

Of course, Verstappen and Hamilton might typically expect their biggest challenges to come from those in the same cars.

However, Sergio Perez played the role of supporting Red Bull team-mate brilliantly in some key moments last year, while Valtteri Bottas continued to do his own thing without worrying Hamilton.

How a change in the Mercedes garage alters things remains to be seen. Bottas has been replaced by George Russell, who will hope to quickly make his mark.

Russell deputised for Hamilton for a single race the year before last and impressed, so it will be interesting to see if he now intends to push his legendary colleague all the way or will initially settle instead for helping his title bid.

Impact of refereeing reform

It is not only the cars that have had a makeover this year, with the officiating structure reorganised in the aftermath of the criticism aimed at Masi.

He is out as race director, with two men, Niels Wittich and Eduardo Freitas, taking his place, while other changes include the introduction of a "virtual race control room" to "assist the race director in the decision-making process".

Whether these changes suitably appease the team principals, who grew increasingly furious with each controversy last year, remains to be seen.

All parties would agree they would rather see the championship decided on the track – but it is not always as straightforward as that.

Following an eventful, dramatic and – dare we say it – the best Formula One season to date, the 2022 campaign has plenty to live up to.

Lewis Hamilton is going in search of a record eighth world title at the second time of asking after missing out to Max Verstappen on the final lap of the final race in 2021.

Reigning champion Verstappen is himself seeking some personal history this coming campaign, which begins with the Bahrain Grand Prix this weekend.

Ahead of what will hopefully be an equally as gripping season this time around, Stats Perform picks out some of the key numbers.

Hamilton narrowly missed out on surpassing Michael Schumacher as F1's most successful driver, though he has not missed out on top spot in successive years since joining Mercedes in 2013.

Should he match his achievement from last year, Red Bull's Verstappen (25 years, two months) would surpass Fernandes Alonso (25y, 2m, 23 days) as the second-youngest multiple world champion, behind only Sebastian Vettel (24y, 3m).

Mercedes may have suffered disappointment last time out, but they still finished top of the constructors' standings for a record-extending eighth time in a row. They are one short of equalling Williams as the second-most successful team, though Ferrari (16) are still well out in front.

In terms of other team milestones, Bahrain will be the 250th GP Mercedes have competed in, while they are six fastest laps away from setting 100. McLaren, meanwhile, are seven podiums from reaching 500 in F1.

Joining Hamilton at Mercedes this season is compatriot George Russell, who along with McLaren's Lando Norris is aiming to become the first Briton other than Hamilton to win a race since Jenson Button in 2012.

Bottas is now at Alfa Romeo and is joined by Guanyu Zhou, who will be China's first ever representative on the grid, making them the 39th country to appear in F1. Indeed, it is the first time three Asian countries will be represented, with Alex Albon (Thailand) and Yuki Tsunoda (Japan) also featuring.

Now 14 years on from their most recent constructors' title, Ferrari will equal their worst-such streak – 15 years between 1984 and 1998 – if they again miss out this term.

Carlos Sainz is Ferrari's big hope and he has either matched or bettered his performance from the previous season – both in terms of points and position – over the past six years when racing for just one team.

While his title chances are slim at best, Fernando Alonso has the opportunity to become the driver with the biggest margin between F1 titles of all time, 16 years on from his most recent success. 

Twenty-two events are currently locked in the F1 calendar for this year, with Miami set to become the 77th different circuit used when it hosts its maiden GP in May. It will be the 11th different track used in the United States, which is the most of any country.

Roma head coach Jose Mourinho has sparked the build-up for Sunday's Derby della Capitale remarking Lazio are off "smoking cigarettes" while his side progressed in the Conference League on Thursday.

The Giallorossi edged past Dutch outfit Vitesse after Tammy Abraham's 90th-minute goal earned a 1-1 draw and 2-1 aggregate victory.

Mourinho said Roma would quickly switch their attention to Sunday's derby with his side in seventh, one point behind Maurizio Sarri's Lazio in fifth.

"Obviously, I am not happy that we played today with many players who will also have to be there on Sunday while tonight Lazio are home smoking cigarettes with Sarri, but it’s because Vitesse are really good," Mourinho told reporters after the game.

Mourinho fielded a strong Roma outfit against Vitesse and given the situation of the tie, with Maximilian Wittek's 62nd-minute goal levelling it on aggregate, he was unable to rest any key players with a quick turnaround for Sunday's derby.

"Now Sarri is at home smoking his cigarette while I go home trying to think how we can recover from this for Sunday," Mourinho said.

He added: "We never came into this to control the result or aim for a draw to get us through. We worked with one objective, preparing to go for victory.

"It was a bad performance on a technical level, it might seem tactical, but it was technical. We defended well and showed character, but we also pushed hard at the end with El Shaarawy as a third striker, not a wing-back.

"I don’t want to say we 100 per cent deserved to go through, but over the two legs did a little more."

After signing a six-year, $120million deal with the Buffalo Bills, future Hall-of-Fame edge rusher Von Miller said it was far from an easy decision.

Miller finished 2021 with 9.5 sacks for the Denver Broncos and the Los Angeles Rams, racking up five for Los Angeles in the final four games of the regular season.

His strong play down the stretch carried into the Rams' triumphant postseason, Miller registering a sack in the wins over the Arizona Cardinals and Tampa Bay Buccaneers before sacking Joe Burrow twice in their victory over the Cincinnati Bengals in Super Bowl LVI.

He finished the season fifth among edge rushers with at least 100 one-on-one matchups with a stunt-adjusted pass rush win rate of 43.40, according to Stats Perform data.

When reflecting about his free agency, Miller said he was surprised with how difficult the decision was.

"I wasn't expecting it to be like that," Miller told reporters. "I was expecting you win the Super Bowl, you got your offers out here, where do you want to go, pick, go back to the Rams. But it was tough man, it came down to the very end.

"I feel like I let [the Rams] down – I feel like I'm breaking up with my girlfriend. That's just me and the way I go about my business. 

"But this was the one time in my life where I had to make a decision for me. I saw what makes Aaron Donald Aaron Donald, and it was hard to walk away from that.

"The only way you can walk away from that is to walk into something special. And what they're doing here is extremely special. 

"[The Bills are] gonna win a Super Bowl with or without me. They've built an amazing team."

While praising his side's win over Galatasaray in the Europa League, Barcelona coach Xavi says it can mean nothing with Sunday's El Clasico in mind.

The Blaugrana will have to back up quickly from Thursday's 2-1 win on aggregate, progressing to the quarter-finals in the process, with a trip to the Santiago Bernabeu against Real Madrid awaiting. 

"Today was an important game, because we are playing for a European trophy," Xavi told reporters after the match. "We want to go far in this competition, and we are very happy to be in the quarter-finals, as we deserve to be there.

"Yes, we are in good form at the moment heading into El Clasico, but that means nothing.

"I have experienced everything about those games, playing badly and then winning or playing well and then they beat us. Sunday will be a different story, a very difficult and complex one."

Barcelona's win in Istanbul was partly clouded by injuries to Sergino Dest and Gerard Pique, who both had to come off in the second half.

With Barca already leading 2-1, Dest produced a desperate but perfectly-timed sliding tackle on Muhammed Aturkoglu in the 55th minute, injuring his hamstring in the process.

Dest’s injury comes at an inconvenient time for club, with Sunday’s Clasico awaiting, and country, with Gregg Berhalter announcing Dest in the United States national team’s latest squad only hours after the final whistle.

Gerard Pique was also a second-half substitute, aggravating a groin injury coming into the match and coming off for Clement Lenglet in the 81st minute.

"In the end he told me that it was difficult for him to sprint and we decided to make the change," Xavi told Movistar+ post-match.

"We weren’t there to give it away. We only won with one goal, and Pique has had discomfort for a month."

Though Dest's status is questionable for Sunday, it is as yet unclear whether Pique will be fit in time for Barcelona's clash against their fierce rivals.

Five-time All-Star Freddie Freeman will leave the reigning world champion Atlanta Braves for the Los Angeles Dodgers on a bumper multi-year deal according to ESPN.

The 2020 National League (NL) MVP has agreed to a six-year, $162million deal with the Dodgers after reaching free agency for the first time in his career.

The 32-year-old has spent his whole professional career with the Braves dating back to 2007, before guiding them to their first World Series triumph since 1995 last year.

California-native Freeman hit .300 with 31 home runs, 83 RBIs and a NL-best 120 runs in their triumphant 2021 MLB season.

The Dodgers' blockbuster move for Freeman follows lucrative deals for Trevor Bauer in 2021 and Mookie Betts in 2020.

Freeman had rejected the Braves' qualifying offer after his contract expired following the World Series triumph, before becoming a free agent in November.

The Braves had signed Matt Olson earlier this week on an eight-year deal, making Freeman's exit more probable, with the Tampa Bay Rays, Toronto Blue Jays and New York Yankees also pursuing him.

The Dodgers are yet to confirm the deal with the move subject to Freeman completing a physical.

"Did that really happen?" Dodgers manager Dave Roberts said on Thursday. "Once Atlanta made that deal for Olson, it kind of came to pass. We're a much better ball club today than we were yesterday."

After his elimination from the Indian Wells Masters, Nick Kyrgios fired back at a reporter who questioned him about an incident after the match where he launched his racket, almost hitting a ball-kid.

Rafael Nadal ultimately emerged victorious in the match 7-6 (7-0) 5-7 6-4, after shaking hands with Nadal and the match umpire, Kyrgios spiked his racket into the ground as he walked back to his bench.

Speaking with post-match media, Kyrgios was sarcastic and rude when questioned about it.

"That's a question you're going to say after a three-hour battle against Nadal – that's what you've come here with?" he said.

"What would you like me to say about it? 

"Obviously was that my intention? No, because did I throw the racquet anywhere near him originally? It landed a metre from my foot and skidded and nearly hit him. I'm human. 

"Things happen like that obviously, it was a very misfortunate bounce. 

"What do you want me to say? It was three metres away from the kid.

Rafael Nadal and Carlos Alcaraz set up an all-Spanish semi-final at the Indian Wells Masters, after both secured wins on Thursday.

Nadal overcame a strong start and comeback from Nick Kyrgios to eventually win 7-6(6-0) 5-7 6-4 in the opening quarter-final, before Alcaraz beat defending champion Cameron Norrie 6-4 6-3.

The Spaniard extended his unbeaten run in 2022 to a staggering 19-0, but the win was not without its share of controversy against the fiery Kyrgios.

A shutout tie-break to end the first was followed by a fiery resurgence from Kyrgios, before he eventually collapsed in the third set and nearly hit a ball kid at the end of the match, when the 26-year-old smashed his racquet in frustration before it bounced up dangerously.

Similarly to his fourth-round win over Reilly Opelka, Nadal used all of his tactical nous to nullify Kyrgios’ serve and power, frustrating his opponent to eventually claim the victory.

"It's difficult to play against him [Kyrgios], always tough because he changes the dynamic of the point very quick and his serve is huge, especially the first serve," Nadal said afterwards.

"I think I played a good third set. Returning better, I was solid with the serve. I just suffered in one game with my serve.

"Nick is one of these kinds of players that you’re going to have problems when he’s motivated."

It was a carbon copy of recent matches between the two, with Nadal eventually waiting for Kygrios’ collapse and pouncing. He now leads their head-to-head battle 6-3.

The win set up an exciting match-up with Spanish starlet Alcaraz, who was brimming with confidence against Norrie in the night game.

The 18-year-old gave the Indian Wells defending champion problems with his characteristically flat two-handed backhand, before opening up the shoulders on the forehand side as the game progressed.

It made up for the fact he only won 59 percent of points on first serve, converting on five of his nine break point attempts.

His stroke play from the baseline was at times thrilling, particularly to set up 15-30 in the fourth game before immediately breaking Norrie back.

On a night where only one NBA game was played, Saddiq Bey made the most of the spotlight, scoring a career-high 51 points in the Detroit Pistons' 134-120 win against the Orlando Magic.

Bey, who at 22 became the youngest in Detroit Pistons history to score 50 points in a game, shot 17-of-27 from the field. This included a scorching 10-of-14 from three, while he also notched up nine rebounds, four assists and three steals.

He is the eighth player to score 50 points in an NBA game this month.

With top pick Cade Cunningham out, former number-two pick and newly acquired Piston Marvin Bagley III enjoyed some extra responsibility, scoring 20 points on 7-of-15 shooting and grabbing 11 rebounds.

Chet Holmgren did his lottery chances no harm with a dominant performance in Gonzaga's 93-72 win over Georgia State, in the first round of the NCAA Tournament.

The 64-team, single elimination tournament – affectionately known as March Madness – is often where players make a name for themselves in front of crowds full of NBA scouts, and for top prospects to prove that they can do it under bright lights. The potential number-one pick in this year's NBA Draft, Holmgren scored 19 points of 8-for-13 shooting.

Holmgren is one of four players who could realistically expect to get picked at number one this year, along with Auburn's Jabari Smith, Purdue's Jaden Ivey and Duke's Paolo Banchero.

As the best player on the tournament's overall number-one seed, Holmgren - who stands at seven-feet tall with a seven-foot-six wingspan - also added 17 rebounds, five assists, seven blocks and two steals as he impacted nearly every possession at both ends of the floor.

Defending champion Sam Burns is one of four players to score a seven-under-par 64, after the first round of play at the Valspar Championship on Thursday.

The world number eight had a busy round on the opening day, with nine birdies and two bogeys. He recovered well after bogey the par-four 16th and reeled off birdies on the final two holes to close out his opening 18 holes.

Following a chaotic weekend at The Players Championship, the Florida weather had a positive effect on the Copperhead course, with Burns reaping the benefits from facilitative greens.

"The greens are really receptive with the rain we’ve gotten last week," he told reporters following his round.

"Yeah, I think the golf course will continue to firm up after we get some sun and wind and I think it’s going to play really well the next few days."

Burns, David Lipsky, Adam Hadwin and Jhonattan Vegas share the lead at Copperhead after the first day of play.

Scott Stallings, Richy Werenski, Davis Riley and Danny Lee are one back at six under, while Justin Thomas, Kramer Hickok and Doc Redman are a further two strokes back.

After missing the cut at TPC Sawgrass, Jason Day opened with a one-under-70, only two weeks after the passing of mother.

Notable names in group at four under include Brooks Koepka, Dustin Johnson, Matt Kuchar and Louis Oosthuizen.

Out of the co-leaders, though, Lipsky was the only one to go bogey-free, opening with a birdie on the par-five first to set the tone on a confident front nine. He closed out the round with four consecutive pars.

The 33-year-old has never won on the PGA Tour and has not won an event since his time on the European Tour in 2018.
