Borussia Dortmund chief Hans-Joachim Watzke insists there's been no formal approaches for Robert Lewandowski.

Manchester United and Bayern Munich are being linked with the Pole.

"There are no enquiries," Watzke told ZDF. "However, I'm aware of the interest in the player, which is normal [considering his quality]. We're in a good situation and we're not forced to sell players.

"When the offers come, we will talk to Robert, but there's a good chance he decides to stay with us. We are playing Champions League and have a good chance to qualify again for next season, I just don't see the necessity to let go any players."
