Thomas Tuchel's view of football was changed by Ralf Rangnick and in Ralph Hasenhuttl he is looking forward to going up against another coach who worked alongside him.

Chelsea head to Southampton on Saturday and Tuchel will pit his wits against Hasenhuttl, who coached RB Leipzig during Rangnick's time as director of football at the Red Bull Arena.

Tuchel was a defender at Ulm for Rangnick between 1997 and 1998 and, following the premature end to his playing career due to a knee injury, was hired as a youth coach at Stuttgart by him two years later.

Rangnick is credited with revolutionising German football by introducing an intense high-pressing, counter-attacking style that was widely adopted.

His influence on Tuchel is clear, with Chelsea allowing the fewest opposition passes per defensive action (PPDA) in the Premier League since his first game in charge against Wolves on January 27.

Across the entire season, Southampton rank fourth in the league with a PPDA of 10.7, behind only Liverpool (10.4), Chelsea (10.3) and Leeds United (8.9).

"I was a player with Ralf Rangnick. I played in the third and second division and learned from Ralf that it's not necessary to follow the striker to the toilet," Tuchel told the media.

"He made a third-division team stronger than we actually were with brand new tactics, the back four not man marking but defending in the space in a 4-4-2 or 4-5-1.

"That was a gamechanger for me to watch football games after my experience with Ralf. It was different because I had a totally different view of what's going on.

"Ralf had his influence at Leipzig when he worked with Ralph as more or less the father of everything that happened in Leipzig.

"There are many coaches influenced by this philosophy, but I truly believe everybody has to find his own style, everybody needs to be authentic. You need to be yourself. You cannot copy anybody.

"The way from Ralph is very impressive. He had a very good season at Ingolstadt, very successful at Leipzig and now a big impact with his aggressive style of playing at Southampton.

"This is the challenge that we have to face. I cannot give you a reason why there is a trend, this is too much of a question for me right now."

Tuchel is unbeaten in six games since taking over at Chelsea, winning five straight since a 0-0 draw with Wolves in his first match.

Olivier Giroud found the back of the net in their 2-0 success over Newcastle United last Monday and Tuchel intends to give the France striker time to stake his claim for a new deal, with his contract due to expire at the end of the season.

Tuchel said: "No decision is made because it's too soon to make these decisions. [It's] too soon in the season and I haven't had enough time to make these decisions because I just started three weeks ago and we need more time to get to know the group better. Everybody deserves more time to show their value.

"What I can say is that I am super happy that he's here. He's one of the top strikers in the box, he's physically strong, he has an incredible first touch and he's strong in headers.

"He did an amazing game against Newcastle. He's very strong, very positive in training, very impressive.

"Right now, he plays a key role in the squad with a lot of young offensive players. He is a key figure, maybe not because he plays every three days 96 minutes, but because of the way he behaves and with his experience on a daily basis, he has a huge impact in the most positive way.

"This is what I can say. When the decision arrives, we will make it."

Only 13 new positive cases of COVID-19 were detected by MLB in its initial round of COVID-19 testing ahead of full-squad spring training, the league announced on Friday. 

The new cases represent 0.3 per cent of the 4,336 intake tests as players and staff reported to team facilities in preparation for spring training games.

Nine of the 13 positive tests were produced by players, while four came from staff members. The 13 positives were spread among 11 teams.

MLB also announced that once players have cleared intake testing they will continue to be tested regularly, and 2,298 additional monitoring tests have been processed without any new positives. 

Pitchers and catchers for all teams had already reported to team facilities in Arizona or Florida. Most clubs plan to start full-squad workouts on Monday, with the first spring training games scheduled for Sunday, February 28.

The 2021 MLB regular season will begin April 1 under a number of coronavirus safety and testing guidelines.

Justin Kluivert was sorely missed by RB Leipzig against Liverpool and his injuries are increasingly frustrating head coach Julian Nagelsmann.

Winger Kluivert joined Leipzig from Roma on a season-long loan at the start of the 2020-21 campaign.

However, the 21-year-old - son of former Barcelona striker Patrick - has so far been limited to just three starts and 452 minutes of action in a Leipzig shirt across all competitions.

An ankle issue has provided Kluivert's latest setback, with his last appearance coming in January and his last start before Christmas.

Prior to being named in the line-up against Werder Bremen on December 12, Kluivert had scored in consecutive matches against Bayern Munich and Manchester United - his only goals so far this season.

Nagelsmann was impressed by the Netherlands international's performances in those games and believes his dribbling ability could be a real asset; he leads Leipzig with 5.4 dribbles attempted and 2.6 completed per 90 minutes this term.

But the coach was again without Kluivert as Leipzig lost their Champions League first leg 2-0 against Liverpool on Tuesday, with the German team attempting just 11 dribbles and failing to execute a single fast break.

"At the stage when we played Bayern and Manchester [United], it was the Justin we were hoping for," Nagelsmann said. "After that, he was gone again.

"He just trains very little, I don't see him much in training. That's the problem. He has to become more stable in terms of his body.

"Since he's been here, he's had far too few training sessions and therefore too little impact on the game.

"He basically has skills that would have done us good in the game against Liverpool. They would also do us good in the Bundesliga, like his deep runs and fast dribbling. He's also a goalscorer and has a good finish.

"But he simply has to become more stable. He's a little too injury-prone these days."

Leipzig would reportedly have to pay in excess of €10million to make Kluivert's move permanent.

Nagelsmann is not ruling out the possibility but would like to see more from the player over the coming months, referring again to the standard set in a 3-3 draw with Bayern.

Kluivert scored with his only shot at Allianz Arena, playing 78 minutes after being named in Nagelsmann's starting line-up.

"Obviously, we hope he has an even bigger impact on a successful season, that he stays healthy and that he can train more and get fit again for the games," Nagelsmann added.

"He's welcome to do as well as he did against Bayern Munich.

"In the course of the second half of the season, we will then decide what we do and what he wants to do. And how big his influence was and how it then continues beyond the summer or not, we will decide then."

Sinisa Mihajlovic has hinted he could be tempted by a Premier League job when he leaves Bologna.

The former Milan head coach recovered from being diagnosed in 2019 with acute leukaemia and has returned to work in Serie A, with his ambitions not limited to Italian football.

Former Yugoslavia international Mihajlovic has a contract until 2023 with Bologna and is in no hurry to move on.

But he is open-minded and, as he prepared to turn 52 on Saturday, the Serbian signalled he was ready to see where fate takes him.

"I live as if I have to stay here 10 years and I work as if I have to leave tomorrow," Mihajlovic said.

"It is not a problem of contracts. I'm fine in Bologna, sometimes I get angry about the results, but I'm fine.

Quoted by Gazzetta dello Sport, he said: "I'd like to see what goals the club has. We have always agreed on everything, I think we will be agreed in the future too, but you never know.

"Do I like the Premier League? I am someone who wherever he goes I want to do my best. Of course, I would like to experience different cultures but I'm not forced to leave. I am used to achieving my dreams when I want."

He added: "There are other things and I would have to live 150 years to accomplish them, and I thought I was dying at 51."

Mark Wood revealed he withdrew from the Indian Premier League auction so he could spend time with his family and to ensure he was not "goosed mentally or physically" in a big year for England.

Wood had put himself forward for an IPL stint at the highest base price (2 crore/£200,000), but opted out on the eve of the auction this week.

The paceman's decision came after he flew to India for the remainder of the Test series, five Twenty20 Internationals and three ODIs.

Wood, who was given time off after the Sri Lanka tour last month, says playing for England in his priority, with the T20 World Cup and an Ashes series in Australia to come after a busy summer on home soil - including facing India again.

The quick said: "I'm going to spend six weeks here in India and then it would be another eight weeks on top of that, so that's 14 weeks.

"We're in a strange situation with COVID and unfortunately you can't see your families during that winter period coming out with India, like we usually do. 

"I just wanted to be able to switch off, recharge and go back home for the second reason, which is being ready for England. 

"I've tried to prioritise that and think later on in the year we've got loads of cricket going on and I don't want my body to fail me or be a bit goosed mentally or physically going into the back of the year, with a World Cup, Ashes and big series against India at home.

"I wanted to make sure I was ready from that point of view and have some family time because this block is a long time away from home."

England all-rounder Moeen Ali was snapped up by Chennai Super Kings for £700,000 on Thursday and although Wood knows he may have missed out on a lucrative deal, the 31-year-old hopes to get another chance to play in the IPL.

"Obviously there's been some big names gone for some big money and never begrudge them that, I think it's life-changing money, so it was a difficult decision for me," he said on Friday.

"The plus side is you're not just going for money reasons, you want to prove [yourself] hopefully going into the World T20 and learn some skills. Plus I feel like I've got a little bit of unfinished business with the IPL, I feel like I didn't do very well well in one game for Chennai last time [in 2018].

"I'd like another crack at some point, I just didn't feel like the time was right. Every player has their own decision, but for me it was to prioritise my family and England."

Antoine Dupont has become the latest member of France's Six Nations set-up to test positive for COVID-19.

Head coach Fabien Galthie, assistant William Servat and another unspecified member of the backroom team have returned positive results since last weekend's 15-13 victory over Ireland in Dublin.

The French Rugby Federation (FFR) announced on Wednesday that no players had tested positive for coronavirus and they had been permitted to return home ahead of further testing on Friday.

Although 11 players returned negative results in the latest batch of testing, Dupont was found to be positive.

"The player who tested positive for COVID-19 is Antoine Dupont," read an FFR statement. "To date, he is asymptomatic. In accordance with protocol he will remain in isolation for the next few days."

The France squad are due to return to the National Rugby Centre in Marcoussis on Sunday to begin preparing for Scotland's visit to Paris the following weekend.

Manchester City have denied reports of a £433million package being proposed to lure Lionel Messi to the Premier League.

Messi is out of contract at Barcelona at the end of this season, having tried to engineer a departure from Camp Nou last August.

During that time, he was heavily linked to City and a reunion with Pep Guardiola, while Barca's appeal to the superstar forward arguably suffered another heavy blow as they were thrashed 4-1 by Paris Saint-Germain in the Champions League this week.

On Friday, The Sun reported Messi had a five-year proposal worth £606m put to him by City before the current campaign, although this figure has been revised due to the wider financial climate of the ongoing coronavirus pandemic and the fact the six-time Ballon d'Or winner will be 34 in June.

However, a club spokesperson told Stats Perform no such offer has been made, nor are there any talks currently ongoing.

Were Messi to sign for City, it looks increasingly likely he would be joining a title-winning side.

Guardiola's men extended their record-breaking winning run for an English top-flight team to 17 matches across all competitions by beating Everton 3-1 in midweek, a result that stretched their lead at the top of the table to 10 points.

Everton boss Carlo Ancelotti said he felt City were "impossible" to play against after a dazzling second-half showing at Goodison Park, where fine strikes from Riyad Mahrez and Bernardo Silva - both players adept in the right-sided attacking roles Messi has filled for large chunks of his career - saw the visitors pull clear.

"I appreciate it, but I don't agree with Carlo, absolutely I do not agree," Guardiola said ahead of Sunday's trip to Arsenal.

"We can lose, the opponents are good and we try to do better than them every single game. This is the only target.

"I love Carlo, he is an incredible inspiration for me as a manager, for many things, but I don't agree with him."

Ilkay Gundogan sat out the Everton game with a groin complaint and Guardiola will make a late call on the Germany playmaker, who has been in sparkling form of late with nine goals in as many Premier League games since the turn of the year.

Gundogan's performances meant Kevin De Bruyne's absence with a hamstring injury was not felt as keenly as might have been expected.

The Belgium star returned from the bench versus Everton and came through will no ill-effects, leaving defender Nathan Ake (hamstring) as City's only remaining senior absentee.

"Nathan is back training on the pitch alone but is closer to coming back with us," Guardiola added.

"Gundo trained just part of the training session today, we'll see how he feels. The rest are fit."

Jurgen Klopp has been suitably impressed by Ozan Kabak so far as the defender looks to make the most of his opportunities at Liverpool. 

Kabak moved to Anfield on the final day of the mid-season transfer window, initially joining on loan from Schalke until the end of the current campaign. 

However, the deal reportedly includes a purchase option, meaning the 20-year-old Turkey international has a window in which to prove he should be signed permanently in a deal worth £18million. 

The centre-back endured a moment to forget on his debut against Leicester City, colliding with goalkeeper Alisson to gift Jamie Vardy a goal that helped the hosts go on to seal a 3-1 triumph at the King Power Stadium. 

Yet Klopp felt Kabak was still solid despite that incident, with the new signing going on to help the Reds keep RB Leipzig at bay in a 2-0 Champions League victory in midweek. 

"Big potential, 20 years old and already pretty experienced, to be honest," Klopp replied when asked about Kabak in his pre-match press conference ahead of the derby against Everton.  

"He didn't take the easy way in his career so far, when you are in Istanbul when you can play for probably one of the biggest teams in the world [Galatasaray] and always be around at the top of the table.

"Then you go to Stuttgart and Schalke, where you have to fight really hard to win football games. That's good from an education and development point of view.

"Now he's here and looks really promising. Both games, he looked really solid.

"Yes, we all know what happened in the Leicester game, but around this situation he played a really solid game, not to forget who we played that day. They were second or third in the Premier League, a tough one with all the forwards they have.

"He did really well - long may it continue."

Kabak has swapped a Bundesliga relegation battle for a top-four fight with Liverpool and, with Fabinho ruled out again, could be set to continue in the team for the visit of Everton on Saturday.

His performance against Leipzig in the first leg of the last-16 tie certainly suggested he has adapted quickly to the change of scenery. He made twice as many tackles (four) as any of his team-mates in Budapest, also managing a joint match-high three interceptions while completing 84.3 per cent of his attempted passes.

The clean sheet on Tuesday was also a confidence boost for Alisson, as his involvement in the Vardy goal against Leicester came after two high-profile errors in the 4-1 home loss to Manchester City. 

While understanding such moments can lead to self-doubt for any player, Klopp made clear to the media that he has never lost faith in his first-choice keeper. 

"My confidence? Nothing changed. We are all human beings, Ali as well. It's not about telling him he's a world-class goalkeeper, he knows that," the Liverpool boss said.

"If you made a mistake in the game before, the previous games and it's nothing you like, humans are all the same. Ali is too smart to ignore it completely.

"Other personalities would perhaps not struggle, but in the end he can rely – and we can rely – on his quality and his attitude, plus how focused he is during a game, how much he lives in it. 

"There was not one second of doubt. Ali, for sure, did not have the best time between the two games – that's how it is. But the Leipzig game was a really good one to get back."

Liverpool are unbeaten in their previous 23 meetings with Everton in all competitions, which is their longest run against any opponent.

They go into the latest meeting with their neighbours looking to avoid a fourth successive league loss, having not suffered such a run of form in the competition since Gerard Houllier was in charge in December 2002.

Daniil Medvedev believes he has "nothing to lose" in Sunday's Australian Open final against Novak Djokovic.

Medvedev reached his second grand slam decider after an impressive 6-4 6-2 7-5 victory over Stefanos Tsitsipas in their last-four clash in Melbourne on Friday.

The Russian fourth seed became the 25th man in the Open Era to record a Tour-level winning streak of 20 as he continued his incredible form.

Medvedev said in an on-court interview all the pressure in the final would be on Djokovic, who has won the Australian Open a record eight times.

Despite seeking his maiden grand slam crown, the 25-year-old – who has won three of his past four meetings with Djokovic – said he had nothing to lose in the final.

"I think he's the favourite because he didn't lose. In eight occasions that he was here in the semis he won the tournament. Me, I'm, how you can call it, I don't know how you call it in English, not an outsider, but I'm the challenger, the guy that challenges the guy who was eight times in the final and won eight times. And I'm happy about it," Medvedev told a news conference.

"I like to play against Novak. We have, since the first one when I was ranked 60, we had always tough matches physically, mentally. And he's one of the greatest tennis players in the history of tennis. So playing the final against him is superb. I'm really happy about it. Let's see what happens on Sunday.

"When I say no pressure, for sure when we get out there we both feel pressure. I want to win my first one. He wants to win number 18. We don't know for who the crowd is going to be. It's all the small details.

"I think if we talk in general, well, I have nothing to lose, to be honest."

Medvedev hit 46 winners and 21 unforced errors against Tsitsipas, overcoming a third-set blip to close out his victory.

As the Rod Laver Arena crowd attempted to get Tsitsipas back into the contest, Medvedev claimed a key break in the 11th game of the third set with a tremendous backhand pass down the line, which he celebrated with a dance.

"They [the crowd] were mostly for him, and that was, you know, the moment that I won the match, we should say. Of course you have to serve after, but that was important moment. So I wanted them to recognise me, I would say, because the shot was unbelievable, I think one of my best shots in my career," Medvedev said.

"Actually, my legs were facing the other way of the court because I didn't have time, so I have no idea how I made this, and I was really happy about it."

Bayern Munich midfielder Corentin Tolisso is a doubt for Euro 2020 after he suffered a serious thigh injury.

The France international did the damage when shooting during a training session on Thursday and underwent surgery on Friday.

Bayern boss Hansi Flick said in a news conference that the former Lyon man will be sidelined for "at least three months".

Stefanos Tsitsipas paid tribute to Daniil Medvedev for his performance in their Australian Open semi-final on Friday.

Medvedev set up a clash against Novak Djokovic in the decider in Melbourne after producing an impressive performance in a 6-4 6-2 7-5 victory over Tsitsipas.

The Russian fourth seed became the 25th man in the Open Era to record a Tour-level winning streak of 20 as he continued his incredible form.

Tsitsipas, who has lost six of seven meetings with Medvedev, credited the 2019 US Open runner-up for his display.

"Everyone saw what just happened out there. I'm the last person you should be asking this," the Greek fifth seed told a news conference.

"I was just focused on my game, and he put out his show. He became Daniil Medvedev for three sets in a row."

Medvedev hammered 46 winners to go with just 21 unforced errors, while dropping serve just once.

He will be aiming for his maiden grand slam title when he faces Djokovic, a player he has beaten in three of their previous four meetings.

"I wouldn't be surprised to see Daniil win the tournament. But, you know, it's a strange scenario," Tsitsipas said.

"I played Rafa [Nadal] here two years ago. I found his performance against me that day phenomenal. I was 100 per cent sure he was gonna win the tournament. And I ended up being wrong.

"Who knows? I don't know. Like, Djokovic is playing well too. Look, I'm not a betting website. I don't know what to say. Might be Medvedev, would be good for him, good for tennis."

Daniil Medvedev produced an impressive performance to outclass Stefanos Tsitsipas in straight sets and book an Australian Open final meeting with Novak Djokovic.

Medvedev was in irresistible form on Rod Laver Arena, needing just over two hours to get past Tsitsipas 6-4 6-2 7-5 on Friday and move into his second grand slam final.

The Russian fourth seed extended his winning streak to 20 matches heading into Sunday, when he will be aiming to claim his maiden major title.

Tsitsipas, coming off an incredible comeback win over Rafael Nadal in the last eight, had the backing of the Melbourne crowd, but no answers to Medvedev, who won for the sixth time in seven meetings between the pair despite a third-set blip.

After an entertaining but largely uneventful start, Medvedev broke for 3-2, a wonderful backhand winner down the line followed up by Tsitsipas sending a forehand just long.

Medvedev was boosted by the break, holding to love in the next game as Tsitsipas' errors mounted, and the Russian closed out the first set despite an increasingly boisterous crowd urging the Greek on.

The baseline exchanges were being dominated by Medvedev, who broke in the third game of the second set on the back of a whipped forehand winner and another down the line.

Medvedev broke to love in the seventh game and he lost just three points on serve in the second set to take complete control.

He continued to dictate points and hit winners at will, breaking serve again to begin the third set, before a blip – a tame forehand into the net seeing Tsitsipas break back, much to the delight of most fans in Rod Laver Arena.

Medvedev saved a break point in the eighth game with an ace down the T to dampen the enthusiasm of the crowd.

He came from 0-30 down to hold for 5-5 in what would prove a key moment, a spectacular backhand pass seeing him break serve – and into a dance – in the following game on his way to victory.

Data Slam: Medvedev in magical form ahead of Djokovic final
Medvedev became the 25th man in the Open Era to record a Tour-level winning streak of 20, and he is just the sixth active player to do so, joining Djokovic, Nadal, Roger Federer, Andy Murray and Juan Martin del Potro. He is also on a 12-match winning streak against top-10 opponents.

Tomi Juric scored a hat-trick of penalties as Adelaide United secured a thrilling 3-2 win over A-League leaders Central Coast Mariners.

In an action-packed contest at Coopers Stadium on Friday, the visitors were undone by a combination of poor discipline and a couple of borderline VAR calls.

The Mariners led with 20 minutes remaining but succumbed to two late spot-kicks, as Juric added to his first-half penalty to end Adelaide's run of three straight losses.

Daniel De Silva gave the Mariners a 15th-minute lead with a scruffy finish inside the box, but the scores were level at the break after Ruon Tongyik was deemed to have fouled Stefan Mauk, with Juric converting from 12 yards after VAR upheld the decision.

Alou Kuol restored the advantage for Alen Stajcic's side, his powerful strike finding its way in off the post, but the lead was short-lived.

Mauk was the one to go down again, with substitute Joshua Nisbet the guilty party, and Juric kept his nerve to beat Mark Birighitti.

Incredibly, the hosts were awarded a third penalty with five minutes left – VAR having spotted a handball by Kye Rowles – and Juric proved deadly once more.

Rowles then saw red deep into stoppage time after remonstrating with the referee as the Mariners missed the chance to go seven points clear at the top.
