Bayern Munich have denied claims they have a deal in place to sign Borussia Dortmund striker Robert Lewandowski.

Reports in Germany this morning suggested Lewandowski had signed a pre-contract with the Bundesliga champions and would move south either this summer — should Bayern agree a fee with Dortmund — or in 2014 when he becomes a free agent.

But a Bayern statement read: “FC Bayern, contrary to these reports, do not have any contract with Robert Lewandowski.”

Dortmund insist they have not received an offer for the Poland international and have put a new deal to the 24-year-old following his virtuoso display on Wednesday, in which he scored four times as Jurgen Klopp’s men thrashed Real Madrid 4-1.

“It would be negligent of us not to try to keep probably the best striker in Europe,” general manager Hans-Joachim Watzke told the Bild newspaper.

“It’s true that we have discussed new conditions once again.”
