Munich - FC Bayern München have confirmed Borussia Dortmund striker Robert Lewandowski will be joining the club this summer after the 25-year-old signed a five-year contract with the record champions.

Lewandowski had a medical in the Bavarian capital on Saturday before signing for the record German title-holders, whom he will join on a free transfer when his current contract with Dortmund expires at the end of June.

Rummenigge: 'One of the world's best'

“We are very happy that this transfer has gone through,” commented Bayern CEO Karl-Heinz Rummenigge. “Robert Lewandowski is one of the world’s top strikers. He will not only strengthen our squad, but his arrival will also give the entire club a boost. We’re delighted that both parties have agreed to a five-year contract until 2019.”

Poland's 2011 and 2012 Footballer of the Year has found the net 65 times in 115 Bundesliga appearances and set up a further 26 goals since joining Dortmund from KKS Lech Poznan in 2010. Lewandowski, who is also the top flight's current joint-top scorer on 11 goals, follows the same route as Mario Götze, who swapped Black and Yellow for Red last summer.
