The 25-year-old was keen on a switch to the Bavarian giants in the close-season, but had the proposed move blocked by Dortmund.

Dortmund – who had already lost star midfielder Mario Gotze to Bayern this year – were insistent that they would not lose another key player to their title rivals and forced Lewandowski, who is under contract until the end of the season, to stay at the club.

Concerns surrounding the player's commitment lingered ahead of the new campaign, but a goal and an assist in a 4-0 win over Augsburg in their opening Bundesliga fixture eased Dortmund fears.

And the rift has been healed after the Poland international reportedly accepted a pay rise of approximately €3.5million.

Lewandowski insists that he is happy at Dortmund and that the disagreement was simply a misunderstanding.

"The situation is now that I will stay in Dortmund for one more year," he told Sport Bild.

"We have put aside all disagreements and have cleared the air. There were mistakes made but the case is closed.

"I had a different starting point. I thought I was allowed to transfer. I was then disappointed and angry. But now everything is calm. I have always said I would respect my contract."

The news is a significant boost to Dortmund, with Lewandowski scoring 36 goals in all competitions last season.

Lewandowski's new strike partner – Gabon international Pierre-Emerick Aubameyang – has scored three goals in two Bundesliga fixtures since arriving from Saint-Etienne.
