The agent of Bayern Munich midfielder Toni Kroos has suggested a summer move away from the Allianz Arena is unlikely despite strong interest from Manchester United.

Kroos is contracted to Bayern until the summer of 2015 but talks over a new deal have stalled with the 24-year-old insisting he will not decide his future until after Germany's World Cup campaign.

The Bayern midfielder has already turned down one offer from the Bundesliga champions, fuelling speculation that he may seek a new challenge in the near future.

After a season where the limitations within their squad have been brutally exposed, United will reportedly make Kroos a lucrative offer this summer after the midfielder recently admitted his admiration for the Premier League.

Despite Kroos' comments, Bayern manager Pep Guardiola and club chairman Karl-Heinz Rummenigge have both insisted a move this summer is off the cards, a sentiment that has been echoed by Kroos's agent Volker Struth.

"For months we've been hearing all kinds of rumours, and we won't comment on them," Struth was quoted as saying by Bild.

"Currently I believe that Toni will play with Bayern until at least 2015."

Should Kroos remain at the club this summer and not sign a new deal, he will be available on a free transfer as of January 2015.

He is likely to line up against United in the second leg of their Champions League quarter final clash at the Allianz Arena on Wednesday with the score poised at 1-1. David Moyes' side defied pre-match expectations as Nemanja Vidic's header have them a surprise lead against the competition's holders before a Bastian Schweinsteiger goal levelled things up.

It was one of the rare occasions this season where Moyes and his side emerged with their reputations enhanced, but the United boss is under no illusions that they must significantly build on that to stand any chance of progressing to the semi-finals.

"The players have to be technically good on the ball," Moyes told the club's official website. "The players need to do better in possession, but I think we need the same spirit and same determination as the first leg to get through.

"We'll need a very good performance from everybody. It's a game where you won't be able to carry any passengers. But it's also a game everyone is really looking forward to. We're really well prepared by beating Newcastle 4-0 at the weekend. The players are going into the game in a good frame of mind.

"We've given ourselves every opportunity and prepared really well. We have to go into this game knowing it's a cup final for us. We want to be in the Champions League final but we have to win this cup final first. From that point of view we can't leave anything [behind] on the night and make sure that we go through."
