Tony Kroos's future at Bayern Munich is in danger as negotiations over a new contract at the Bundesliga side have reportedly stalled, adding to his frustration after manager Pep Guardiola decided to leave him on the bench during the latest fixtures.

The 24-year-old talented midfielder has entered the final 18 months of his contract and this summer would be Bayern's last chance to reap a profit from his sale – with Manchester United, City, Chelsea, Arsenal and Liverpool reportedly interesting in his services.

The Red Devils were reportedly in pole position to sign Kroos during the last transfer window but Daily Mail claims that David Moyes's side will have to face competition from the rest of the Premier League giants who also want to take advantage of his contract situation to secure the services of one of Europe's most talented midfielders.

Last month, reports revealed that Kroos already rejected an extension offer to commit his future to Bayern and Mail reports that negotiations are still stalemated because of the player's huge salary demands. Kroos' weekly wages is currently between £50,000 and £80,000 but he is demanding for £150,000 to enter the same bracket as Philipp Lahm, Bastian Schweinsteiger and Franck Ribery.

Bayern has refused to meet his asking price and it looks like Kroos's issues with the German club regarding a possible contract extension is also affecting his standing in the team – with the player expressing his anger after being substituted against Stuttgart recently. Manager Guardiola responded to his petulance by leaving him on the bench in their 5-0 victory over Eintracht Frankfurt last Sunday, when Thiago Alcantara, who replaced him, excelled.

Indeed, the Bayern boss recently suggested that the midfielder may leave the team next summer.

"He is an important player for us but in football things can go fast. One day you are here and the next you are there..."

At the same time, Kroos himself also opened the door to a potential move away from the Allianz Arena.

"I am unable to rule anything out. I am under contract with Bayern Munich. Actually there are yet no further talks (regarding a new contract) scheduled. I will therefore fully focus on the second half of the season."
