Manchester United have been encouraged in their reported pursuit of Bayern Munich midfielder Toni Kroos.
The Germany international has put a number of clubs across the continent on alert after revealing talks with the Bundesliga champions over a new contract have faltered, with his current deal set to expire in the summer of 2015.
Despite featuring in 18 of Bayern's league games this season there are severe doubts regarding the midfielder's future, which intensified on Wednesday evening when he reacted angrily to being substituted after an hour with his side trailing 1-0 to Stuttgart.
The 24-year-old's departure would go on to fuel a Bayern comeback, with his replacement Claudio Pizzaro grabbing an equaliser before the champions went on to clinch a 2-1 win thanks to a wonderful last minute scissor kick from Thiago Alcantara.
Bayern manager Pep Guardiola did little to quell speculation suggesting Kroos may leave the club. Before the game the former Barcelona manager was quizzed on the future of the 24-year-old, telling reporters: ""He is an important player but things can move fast in football. Here today, gone tomorrow."
Kroos has already turned down an offer of a new contract from the Bavarian giants and refused to rule out the possibility of a move away from the Allianz Arena.
"I am unable to rule everything out. I am under contract with Bayern Munich. Actually there are yet no further talks (regarding a new contact) scheduled. I will therefore focus on the second half of the season.
"There are worse situations in life. I play for a top club, and under a top coach. I am pleased and sometimes in the future a decision will be made."
Despite Guardiola's suggestions that a move away is a real possibility, Bayern chairman Karl-Heinz Rummenigge suggest Bayern are desperate to retain Kroos despite the current stalemate between the club and player.
"I hope that we will come up to an agreement with Toni," Rummenigge told Bild. "He is a player we basically want to keep happy. Now we must look if we are making a contract, in the last analysis, to satisfy Toni as well as FC Bayern."
Reports in the German press suggest Kroos, who reportedly earns €4m a year, wants an offer equal to that of Bayern's top earners Mario Gotze and Bastian Schweinsteiger which Bayern are reluctant to match. However the Daily Mail suggest United will have no qualms offering the midfielder a deal worth £150,000 a week and will test Bayern's resolve with an opening offer of £25m before Friday's transfer deadline.
