Former Germany international Lothar Matthaus claims Borussia Dortmund striker Robert Lewandowski has agreed to join Bundesliga rivals Bayern Munich in the summer.
Lewandowski has reportedly told Dortmund he will not extend his contract with the club, which expires in 2014. The reigning Bundesliga champions are consigned to losing their leading striker in the summer, and are willing to sell up in order to secure a fee for one of their most prized assets.
However the Red Devils may miss out once more after Matthaus, who made over 300 appearances for Bayern in two spells while also winning 150 caps for Germany, revealed Lewandowski could complete a summer move to his former club for a fee in the region of "£20m to £25m".
"I was on the road this week. I heard that Lewandowski has an agreement with Bayern. Only the date of the move remains undecided," the 1990 World Cup winner told Sky Bundesliga.
"Lewandowski’s contract runs out in 2014 and Dortmund will only get a fee in 2013 - surely a high fee. I heard it was something between £20m-£25m, otherwise he will go to Bayern for free next year."
Matthuas' comments have angered Bayern Munich President Uli Hoeness, who criticised the 51-year-old's decision to speak out about the club's affairs.
"Lothar Matthaus has become active again in recent months. It was always with women and now he is suddenly discussing new players at Bayern. It seems that he has changed his hunting field somewhat," he told Sport1.
"Why should we deny things that do not concern us at the present? We have no desire to constantly deny any rumours. We focus only on our work and not rumours."
Lewandowski, who scored and was sent off in Dortmund's 4-1 defeat aginst Hamburg on Saturday, could become Pep Guardiola's first signing as Bayern boss when he takes charge of the Bavarian club in the summer.
The former Barcelona coach has agreed to take over from current boss Jupp Heynckes on July 1.
