Barcelona have announced the transfer of Bayern Munich striker Robert Lewandowski.

Lewandowski has joined Barcelona from Bayern Munich, with the Catalan club to pay a fixed fee of 45 million euros and a potential 5m euros more in add-ons.

Although the German club had stood firm and insisted that they wanted 50m euros for the player who still had one year on his Bayern contract, they eventually agreed to accept the 45m euros plus 5m euros structure.

The Catalan club put out a statement on their official website, shortly after Bayern Munich directors had also confirmed the deal.

"Barcelona and Bayern Munich have reached an agreement in principle for the transfer of Robert Lewandowski, dependent on the player passing a medical and contracts being signed," Barcelona's statement read.

"The striker from Poland stands out for his goalscoring abilities. Inside the box he has all the tools to make him a difficult striker to read as he can find the net with his head and both feet with equal precision.

"His technical qualities also mean that he can link up well outside the box also. Lewandowski will bring goals, experience and know-how to the Barcelona attack."
