Bayern Munich coach Pep Guardiola has refused to discuss striker Robert Lewandowski until he joins up with his side next season.

Lewandowski agreed a deal to join Bayern on a free transfer at the end of the season on Saturday, signing a five-year contract with the German champions.

However, Guardiola does not believe that it would be right to discuss the Polish striker while he is still a Borussia Dortmund player.

"Lewandowski is a player for next season. I can talk about him next season," Guardiola told reporters.

The German season is currently on its winter break, with Bayern leading the way in the Bundesliga table by seven points with a game in hand over second-placed Bayer Leverkusen.
