Toni Kroos has been urged to stay at Bayern Munich by ex Munich manager Jupp Heynckes, according to Goal.
Kroos, whose contract runs out in 2015, has been widely linked to a number of high profile clubs with Manchester United appearing to be the front runners.
Kroos was a part of last season's German treble winning side, which included the Bundesliga title as well as the Champions League.
The former Bayern coach reportedly told Kicker: "He shouldn't leave Bayern, not even for Barca or Madrid.He can win everything with this side in the next four years and needs to be playing as the head of the team."
His comments come after revelations by Kroos' brother, suggesting that the Bayern midfielder may be looking for a summer exit to Old Trafford.
Felix Kroos, who currently plays for German side Werder Bremen, told Sky Germany: "We have already talked about it. Manchester has been the team of my dreams since I was a child. However, I do not give him any advice."
"He will take a good decision for himself. There are worse situations than having to decide something like that."
The German has appeared to have been a target for United manager David Moyes to help solve their current midfield crisis.
Despite soon being out of contract, Kroos has been in impressive recent form and the German champions might not let him leave the Allianz Arena so easily.
