Borussia Dortmund striker Robert Lewandowski will join Bayern Munich in the summer after the player's agent Cezary Kucharski confirmed the Polish international will be following Mario Gotze to Allianz Arena.

"Robert will join Bayern this summer. There is no point in pretending that he will not move to Bayern. Robert wants to leave and that is what will happen. It is a matter of time. It could be a done deal within a week or within two to three weeks. We are waiting for a signal from the club. We are working on this deal," Kucharski explained.

"Robert needs a new challenge. He needs other people around him, a new coach and new motivation," Lewandowski's agent added.

Lewandowski last featured for Dortmund against his future club in the Champions League finals last weekend. Kucharski's comments come just over a day after Bayern's outgoing manager Jupp Heynckes confirmed the Pole will join the Bundesliga champions next season.

"We know Mario Gotze will be joining us and I don't think Lewandowski will be hanging about too much either," Heynckes said.

The timeline of events which took place in the last few weeks has not convinced Dortmund CEO Hans-Joachim Watzke, who publicly criticised Heynckes for his comments made on Lewandowski's transfer saga.

"Jupp Heynckes should stay out of this and concentrate on the line-up for next Saturday [for the DFB-Pokal final against Stuttgart]. I don't know how close Heynckes is to the management of Bayern. But if they want to have Lewandowski it would be good if we were told about this," Goal.com quoted Watzke as saying.

Bayern is currently having Thomas Muller, Mario Mandzukic and Mario Gomez as the senior strikers to lead their attacking division. However, the latter is likely to leave the German outfit after his agent confirmed the German international is unhappy with the lack of playtime at the club.

Lewandowski's addition to Bayern's squad will strengthen their striker force and at the same time it will be a blow for Manchester United, who were also interested in his services. However, this could come as a relief for Liverpool fans after their star player Luis Suarez was a top target for the former Barcelona manager Pep Guardiola, who will take in charge of the club from the next season.
