Matthias Sammer "delighted" with Robert Lewandowski deal

Bayern Munich director of sport Matthias Sammer has expressed his delight at having wrapped up a deal to bring Borussia Dortmund striker Robert Lewandowski to the club.

Lewandowski will join Bayern on a free transfer at the end of the season having agreed a five-year contract with the German champions on Saturday.

"It's a big transfer for Bayern and we're delighted that it's come off, but we all agree that enough has been said about it," Sammer told the club's official website.

"Robert Lewandowski is a Borussia Dortmund player and he should now concentrate on his current club. I'm no longer going to say anything on the issue either.

"Robert Lewandowski only becomes a subject of discussion at Bayern Munich from next summer."

Lewandowski, 25, has scored 81 goals in 146 matches for Dortmund.
