Shkodran Mustafi has signed a short-term contract at Schalke after leaving Premier League side Arsenal.

Mustafi's deal at Emirates Stadium was due to expire in June and the Germany defender will now play out the remainder of the current campaign back in his homeland with Bundesliga strugglers Schalke.

The 28-year-old joined the Gunners from LaLiga outfit Valencia in 2016 and leaves with two FA Cup winners' medals.

However, Mustafi fell down the pecking order at Arsenal and only three of his 2020-21 appearances have come in the Premier League after recovering from hamstring surgery.

"Musti has been a key player for us for a long period of time," said Arsenal manager Mikel Arteta.

"He played a very important part in my first season as manager and I'd like to thank him for his professionalism and for always being ready when called upon.

"Everybody at Arsenal wishes Musti well at Schalke."

Mustafi will be reunited with Sead Kolasinac, who is on loan at Schalke and embroiled in the fight to help the Bundesliga's bottom club avoid relegation.

A World Cup winner in 2014, Mustafi arrives in Gelsenkirchen as a replacement for Ozan Kabak in Christian Gross' squad after the Turkey international joined Premier League champions Liverpool on loan until the end of the season.

Liverpool have made their second defensive signing of transfer deadline day by bringing in Ozan Kabak from Schalke on loan.

Sami Khedira hopes to repay Hertha Berlin for bringing him back to the Bundesliga by helping the club enjoy success on the pitch. 

The German midfielder has returned to his homeland to try and kick-start his career having been frozen out at Juventus this season. 

Khedira won five Serie A titles during his time with Juve but featured sparingly across the previous two campaigns as he was hampered by injury issues.

However, the 33-year-old – who was part of the Germany squad that won the 2014 World Cup – insists he is fit and ready to get back playing again with Hertha, who have struggled so far this term. 

"Hertha made great efforts to sign me and offered me the opportunity to return to the Bundesliga," Khedira said. 

"I'm grateful for that and I honestly cannot wait for the moment when I'll be wearing the blue and white shirt on the pitch for the first time. 

"I feel great physically would like to use the experience I have gained in recent years to help the team and lead Hertha to more sporting success."

Khedira won the Bundesliga with Stuttgart in 2006-07 and also had domestic and European success during his time with Real Madrid, including lifting the Champions League trophy in 2014. 

Now, though, he has joined a Hertha side that sit just above the relegation places. They recently made a coaching change, bringing back former boss Pal Dardai to try and improve their fortunes. 

"Sami Khedira is a successful leader on the pitch and a name that is recognised around the world. I am delighted that we have been able to bring him to Hertha BSC," said Hertha CEO Carsten Schmidt. 

"I am convinced that with his personality on and off the pitch, he will give our young team the stability it needs to be successful."

As well as Khedira, Hertha also confirmed the arrival of winger Nemanja Radonjic from Marseille on deadline day, initially on loan for the rest of the season but with an option to buy. 

Will he stay or will he go?

That is the question regarding Paris Saint-Germain star Kylian Mbappe, who is a reported target for Real Madrid and Liverpool.

If Mbappe opts to call time on his PSG stall, the French champions are still aiming high.

TOP STORY – LIFE WITHOUT MBAPPE IN PARIS?

Paris Saint-Germain are more determined than ever to give head coach Mauricio Pochettino a dream forward line amid doubts over Kylian Mabppe's future, according to Le10 Sport.

Mbappe – out of contract in 2022 – has been heavily linked with LaLiga champions Real Madrid and Premier League holders Liverpool.

If Mbappe does not remain in Paris, PSG will step up their pursuit of Barcelona superstar Lionel Messi.

ROUND-UP

- Massimiliano Allegri has turned down Roma as he waits for Madrid, repots Todofichajes. Zinedine Zidane is under mounting pressure in the Spanish capital, while it is a similar situation for Roma boss Paulo Fonseca.

- Manchester City are willing to sign a striker and Messi this offseason, according to The Athletic. With City yet to offer Sergio Aguero a new deal, Borussia Dortmund's Erling Haaland and Inter pair Lautaro Martinez and Romelu Lukaku are reported targets as Pep Guardiola's side also eye soon-to-be free agent Messi.

- Fabrizio Romano says Liverpool have agreed to sign Ben Davies from Preston North End ahead of Monday's deadline day. Jurgen Klopp has been eyeing a defender due to the club's injury crisis.

- Dele Alli's proposed switch from Tottenham to PSG is not progressing, reports Romano. Struggling for game time at Spurs, Alli has been keen for a loan move to PSG, but Tottenham are unwilling to sanction a departure as Inter block Christian Eriksen's return.

- Leicester City are the frontrunners to sign Arsenal's Ainsley Maitland-Niles, claims The Mirror.

Bayer Leverkusen have confirmed the signing of winger Demarai Gray from Premier League side Leicester City.

Gray joined Leicester from Birmingham City midway through 2015-16 and went on to help the Foxes to a sensational title triumph that season.

He went on to feature 133 times in the top flight, scoring 10 goals and providing nine assists, but never really established himself as a first-team regular under Brendan Rodgers.

With his contract at Leicester having been set to expire at the end of 2020-21, Gray – who was linked with a number of Premier League clubs – has made the move to Germany.

The 24-year-old made just one league appearance this term, totalling 18 minutes, and joins a Leverkusen side who sit fourth in the Bundesliga.

Leverkusen had looked ready to mount a title challenge this season, but a run of just one win in seven games has seen them drop off the pace.

Gray has only committed to Leverkusen until June 2022 but is confident he will flourish in the Bundesliga – a league in which English talents have fared well in recent years.

Jadon Sancho has become a star at Borussia Dortmund, where Jude Bellingham, another former Birmingham youngster, is also impressing, while Reiss Nelson and Ademola Lookman have shone in loan spells at Hoffenheim and RB Leipzig respectively. Lookman struggled after a permanent move, however.

"I saw Bayer playing attacking football, going forward aggressively and dictating the game with possession," Gray said.

"I'll fit in well. I can and would like to develop myself further here and be successful with this attractive team."

WHERE WILL HE FIT IN?

While Gray has had little chance to show his quality this season, he will bring an extra option to a vibrant, youthful Leverkusen attack and could be vying for a place with Leon Bailey.

After struggling for consistency last season, Bailey has enjoyed something of a resurgence this term, scoring four goals and creating five more in 18 Bundesliga games.

Bailey's 26 chances created rank fourth in Leverkusen's squad, with 17-year-old sensation Florian Wirtz (31), Moussa Diaby and Nadiem Amiri (both 27) ahead of him.

Gray may also find himself going up against former Paris Saint-Germain forward Diaby for a starting berth.

The 21-year-old has created a team-high seven big chances for Leverkusen in the Bundesliga, however, with his rapid pace a major outlet for Peter Bosz's side.

Gray is Leverkusen's third signing of the January window, following defenders Timothy Fosu-Mensah and Jeremie Frimpong, signed from Manchester United and Celtic respectively.

Sami Khedira is in talks with Hertha Berlin over a return to the Bundesliga, the German club's chief executive has confirmed.

Juventus midfielder Khedira is expected to leave the Serie A champions before the transfer window closes on Monday.

The contract extension the World Cup winner signed in 2018 is up at the end of the season, but he is set to depart early having failed to appear in a single matchday squad for Juve this term.

Khedira initially had a big impact after joining the Turin club in 2015, scoring 19 goals in 77 games across three successive title-winning Serie A campaigns.

He has since played just 22 times in the competition, suffering with injuries and falling out of favour entirely under rookie coach Andrea Pirlo.

Khedira spoke of a potential move to the Premier League ahead of January, but Berlin and Hertha – 14th in the Bundesliga – now appears his most likely destination.

Hertha CEO Carsten Schmidt told Sky Sport: "Yes, we are having talks with Sami Khedira. I can confirm that. I also spoke to him on the phone.

"We are dealing with it, but there are still a few things to be clarified, of course. We still have many questions to answer."

But Schmidt would not comment on Hertha's reported interest in Werder Bremen attacker Milot Rashica.

Rashica has been hindered by knee and thigh problems this season, playing just 379 minutes in all competitions and failing to score. He has provided a single assist from five chances created.

Sergio Ramos is reportedly set to quit Real Madrid and is eyeing Manchester United, while David Alaba is apparently not a target for Manchester City.

Ramos, 34, seems set to leave Madrid at the end of the season with his contract expiring.

With the defender appearing no closer to agreeing to a new deal, he could make the move to the Premier League.

TOP STORY – RAMOS TO QUIT MADRID, EYES MAN UTD

Ramos is ready to quit Real Madrid and his camp are set to target Manchester United as his next destination, according to the Mirror.

Manchester City, Liverpool, Paris Saint-Germain and Everton have also been linked with the defender.

Ramos has been at Real Madrid since 2005, winning five LaLiga titles and four Champions Leagues among numerous other honours.

ROUND-UP

- Another defender set to move at season's end is David Alaba, with the Bayern Munich star linked with numerous European giants as his contract comes to an end. But 90min reports Manchester City will not be making an approach for the Austria international.

- Amid an injury crisis at centre-back, Liverpool could sign a defender before Monday's transfer deadline. The Evening Standard reports they are interested in Arsenal defender Shkodran Mustafi, who is out of contract at the end of the season.

- Arsenal may not be done in this transfer window, either. The Mirror says Arsenal are considering a move for Crystal Palace left-back Patrick van Aanholt.

- Marcos Rojo is set to get a Manchester United exit. Sky Sports reports the defender will terminate his contract, which was due to expire at the end of the season, before joining Boca Juniors on a free transfer.

Bayern Munich's display in their 4-1 rout of Hoffenheim set the standard for the rest of the season, according to Hansi Flick.

Jerome Boateng, Thomas Muller, Robert Lewandowski and Serge Gnabry struck as Bayern cruised to a fourth straight Bundesliga victory – their second-longest winning run of the season after they won five games on the spin between matchweeks three and seven.

Munich have now scored 57 goals in the league this term, a club record after 19 games, while the only other side to have scored more after the same amount of fixtures was Hamburg in 1981-82 (58).

It lifted Bayern, briefly at least, 10 points clear at the top of the table, with the signs looking ominous for the rest of the league as the Bavarian giants chase down a ninth successive title.

"You are used to the fact that both teams want to play football. Hoffenheim has also shown that and created opportunities, especially in the first half," Flick told Bayern's official website. 

"It is a very good result. We have now won four games in a row – 12 points. We played a good game, that is our benchmark.

"Certainly not everything was great, but I'm satisfied. We wanted to get back on track after the two defeats. That's what makes big teams. This is a good thing and gives you confidence."

Lewandowski was typically integral to Bayern's win, setting up Muller for his 10th Bundesliga goal of the season before the Poland star helped himself to a 24th top-flight strike of 2020-21 early in the second half, the most of any Bundesliga player in history after 19 games.

His strike partner Muller was also at his industrious best, with the 31-year-old having hit double figures in the league for the first time since 2015-16, when he scored 20.

"After four wins from four games you can say that we are on the right track," Muller said.

"In large phases of the game, we repeatedly showed serious actions both in the front and in the back. If we pick up the pace, we often end up in good situations. 

"Of course we would have liked to not concede a goal. It was good and creative up front. We would have deserved one more goal."

One player to miss Saturday's win was Corentin Tolisso, who has been fined by Bayern after breaching the club's coronavirus protocols in order to get a tattoo.

"We're grateful that games can currently take place in the Bundesliga despite the ongoing coronavirus situation. A condition of that is that players, coaches and staff must adhere to the DFL's hygiene concept in an exemplary manner," said Bayern CEO Karl-Heinz Rummenigge.

"Corentin Tolisso has now contravened these guidelines, although our sporting and medical leadership continuously and clearly communicate them. We won't tolerate violations like this. We will therefore hand Corentin Tolisso a heavy fine, which will be donated to charity."

Tolisso's omission from the squad came after Leon Goretzka and Javi Martinez tested positive for COVID-19.

Robert Lewandowski scored one goal and made another as Bayern Munich increased their lead at the top of the Bundesliga with a 4-1 victory over Hoffenheim.

The defending champions nosed, briefly at least, 10 points ahead of RB Leipzig as they aim to secure a ninth successive title.

Hoffenheim offered plenty of threat and Ihlas Bebou should have done better with two gilt-edged chances, with his profligacy punished by Jerome Boateng and Thomas Muller.

Bebo atoned by teeing up Andrej Kramaric to volley in his first away league goal at Bayern on the stroke of half-time, but quickfire strikes from Lewandowski and Serge Gnabry ensured a fourth straight Bundesliga win for Hansi Flick's team.

Hoffenheim stunned Bayern 4-1 early in the campaign and Bebou could have put them ahead in the opening stages on Saturday, but Manuel Neuer came to the hosts' rescue.

Though Muller hit the crossbar at the other end, it was Hoffenheim who should have taken the lead – Bebou heading wide from close range – and he was made to pay in the 32nd minute when Boateng headed in Joshua Kimmich's outswinging corner.

Bayern seemed to be heading into half-time with a two-goal cushion when Muller's rather scuffed effort at the culmination of Lewandowski's mazy run found its way into the bottom-right corner, yet Hoffenheim struck back 74 seconds later when Kramajic steered Bebou's cross beyond Neuer.

Unperturbed by conceding, Bayern were straight back on the front foot after the restart and their third goal came shortly before the hour, with Lewandowski on hand to capitalise on poor defending.

Kingsley Coman's cross had caused havoc in the build-up to Lewandowski's 24th league goal of 2020-21 and the Frenchman turned provider again six minutes later as he slipped in Gnabry to wrap up the points.

Benjamin Pavard thought he had added further gloss with a sensational strike from 20 yards out, only for VAR to disallow it due to Leroy Sane drifting offside, with Neuer pulling off an exceptional save to deny Pavel Kaderabek a late consolation.

What does it mean? Bayern looking ominous

With RB Leipzig featuring in Saturday's late Bundesliga game, Bayern could enjoy, however briefly, the feeling of being 10 points clear.

Despite some defensive lapses proving costly this season, Bayern simply have far too much going forward for the rest of the league to handle. They have already scored 57 goals across their 19 Bundesliga games, and they have never let such a big lead slip in the second half of a season since the introduction of three points per win.

Muller and Lewy lead the way

Lewandowski is still Bayern’s talisman, but he is being superbly supported by Muller, whose resurgence under Flick has been a joy to behold.

Poland star Lewandowski toyed with Hoffenheim's defence before laying it off to Muller to drag in Bayern's second. Muller has now hit 10 goals in the league this season, his best tally since the 2015-16 season (20).

Bebou shows his best and worst

Bayern struggled to cope with Bebou's pace and power in the early exchanges, but the Hoffenheim forward really should have done better with his chances – the two attempts he managed.

On the other hand, Sebastian Hoeness will take the positives from the 26-year-old creating a joint team-high three opportunities, including his superb assist for Kramaric's volley.

What's next?

Bayern travel to Hertha on Friday, while Hoffenheim host Eintracht Frankfurt two days later.

Robert Lewandowski scored one goal and made another as Bayern Munich increased their lead at the top of the Bundesliga with a 4-1 victory over Hoffenheim.

The defending champions nosed, briefly at least, 10 points ahead of RB Leipzig as they aim to secure a ninth successive title.

Hoffenheim offered plenty of threat and Ihlas Bebou should have done better with two gilt-edged chances, with his profligacy punished by Jerome Boateng and Thomas Muller.

Kylian Mbappe's future continues to dominate headlines.

For so long, Real Madrid have been favourites to prise Mbappe to the Santiago Bernabeu.

But Premier League champions Liverpool are believed to be stepping up their pursuit.

TOP STORY – LIVERPOOL FRONTRUNNERS FOR MBAPPE

-  United are eyeing Barca's Ousmane Dembele if Borussia Dortmund star Jadon Sancho does not arrive ahead of the 2021-22 campaign, according to Falk.

Bayern Munich have confirmed Leon Goretzka and Javi Martinez have tested positive for coronavirus.

They will be unavailable for Saturday's Bundesliga match at home to Hoffenheim.

The European champions then face Hertha Berlin away on February 5 before their Club World Cup campaign starts three days later.

Goretzka has made 20 appearances in all competitions this season, while Martinez, 32, has played 18 times, mostly as a substitute.

Bayern also confirmed goalkeeper Alexander Nubel is likely to be out of action for up to a month.

The former Schalke man, who has only played twice this season, suffered ankle ligament damage on Thursday.

Chelsea are reportedly interested in Borussia Dortmund star Erling Haaland and Bayern Munich defender David Alaba. 

Haaland and Alaba have been linked with moves, with the latter almost certain to leave Bayern when his contract expires at the end of the season. 

Chelsea spent big last year – but they are apparently eyeing the pair.

TOP STORY – CHELSEA INTERESTED IN HAALAND AND ALABA

Chelsea are interested in signing Dortmund star Haaland and Bayern defender Alaba ahead of 2021-22, according to Sky Sports.

Real Madrid have been strongly linked with the duo, while Alaba is said to be a target for several other European giants.

Thomas Tuchel has replaced Frank Lampard at the helm for Chelsea, who are eighth in the Premier League.

ROUND-UP

- Jesse Lingard could join West Ham. Sky Sports reports they have offered a £1.5million loan fee and to pay Lingard's wages for the rest of the season to land him on loan from Manchester United.

- Amid reports Lucas Torreira could leave Atletico Madrid, where he is on loan from Arsenal, to join Monaco, it seems that may not be the case. Fabrizio Romano reports Monaco are not negotiating for Torreira.

- Bayer Leverkusen are confident of completing a deal for Leicester City midfielder Demarai Gray, according to Sky Sports.

- Struggling for game time at Arsenal, Ainsley Maitland-Niles could make a move. The Athletic reports West Brom are looking at the 23-year-old for a potential loan deal.

Kai Havertz has all the qualities to be "world class" but was always likely to need time to settle in at Chelsea, according to Bayer Leverkusen's sporting director Simon Rolfes.  

The Blues spent a reported £72million (€80m) to bring the Germany international from Leverkusen in September, yet he has so far struggled to justify the hefty price tag.  

The attacking midfielder was one of several big-money signings during a busy close-reason recruitment drive, with compatriot Timo Werner - who arrived from RB Leipzig - also enduring a difficult start to life at Stamford Bridge. 

Havertz has managed five goals and five assists, as well as 23 chances created (1.4 per 90 minutes) and five big chances created (0.3 per 90) in 25 appearances so far in 2020-21.  

For comparison, during his final season at Leverkusen, he registered 18 goals (0.43 per 90), nine assists (0.21 per 90), 84 chances created (1.99 per 90), 20 big chances created (0.47 per 90) from 45 appearances.  

Chelsea's struggles on the pitch this term saw club legend Frank Lampard sacked and replaced by Thomas Tuchel, and Rolfes feels it is unfair to focus purely on Havertz, who he is backing to show his true abilities in the Premier League.

"It's always difficult if you change country and a little bit of a different style. That's the same if we sign players," Rolfes told Stats Perform News. 

"Some players need two days, some guys need half a year. For example, Moussa Diaby needs three-four months to adapt from France, although he was playing for PSG, to adapt to the Bundesliga.  

"You have to have in mind when you sign players, that not everybody is directly from the first day there.  

"I've followed Chelsea a little bit from a distance, but it's not only Kai or Timo Werner struggling a little bit, it's also the team – they expected more from the whole squad.  

"That's not so easy if it's not working in the team and you come in as a new player. It's much easier if the team is working and you step in your best position.  

"That's a process for Kai, to adapt to England and the Premier League. There is no doubt Kai is a fantastic player and has all the ability to play on the world-class level and although it's probably not his best six months, there is no doubt in my opinion."

Kylian Mbappe wants time to make a decision on his future as Real Madrid await a signal from the Paris Saint-Germain star.

Mbappe, 22, has been linked with a move to Madrid and his contract at PSG ends in 2022.

But will the forward end up at the Santiago Bernabeu?

TOP STORY – REAL MADRID WAIT FOR MBAPPE

Real Madrid are waiting for a signal from Paris Saint-Germain star Kylian Mbappe, according to Marca.

The report says Mbappe has asked for time to decide his future.
