The Polish international forward is one of the most lethal in Europe and has been linked with Bayern Munich and Man Utd.

Lewandowski told Sport Bild: "I have two more years on my contract. That is a long time. I don’t have to decide today whether to renew or not. I am not setting myself a limit.

"I do not know what will happen after the season. I cannot and don’t want to rule anything out."
