Borussia Dortmund striker Robert Lewandowski has revealed that he has decided where he will be playing his football next season.

The 25-year-old, who is regarded as one of the best forwards in European football, will be out of contract at Dortmund at the end of the season.

Bayern Munich and Chelsea have both been strongly linked with his services, but the Pole has claimed that his mind is already made up.

"I am feeling very well at Dortmund, but I want a new challenge next season," he told Sport Bild.

"I can only say one thing about my future and that's that I will announce my decision next year. No club has to bother with a fresh approach. I am focused on Dortmund and will not let anything distract me."

Lewandowski has scored 13 goals for his club this season.
