Manchester United are ready to use Anthony Martial as a pawn in negotiations for Bayern Munich striker Robert Lewandowski.
The Sun says the German giants have been keeping tabs on United's French winger, and are keen on landing him this summer.
The Red Devils want at least £70m for the 22-year-old, but Bayern are not willing spend more than £50m.
United boss Jose Mourinho is a huge fan of their Poland striker, and has tried to bring him to the club in the past.
And Old Trafford chiefs will try to land the 29-year-old in a player plus cash exchange.
A source said: “Bayern are still keen and United have been after Lewandowski for a long time and want him.
“His agent is close to Jose and United and he is keeping them both in the loop along with Real Madrid.
“This is all down to whether he wants to go and Bayern are happy for him to leave. It's up in the air.
“Bayern want Martial to take over from Ribery but don't want to pay the excessive fee being asked for."
