Arsenal have set their asking price for Hector Bellerin.
CBS Sport says the Gunners have told all parties interested in Bellerin they must cough up at least £20million for the Spaniard, it's claimed.
And with Atletico Madrid waiting to pounce, it could see Kieran Trippier move to Manchester United.
Atletico were said to be considering a swap deal involving Trippier and Bellerin.
But Trippier has told his England team-mates he wants to move to Old Trafford.
As a result, Atletico have been told to cough up the dough if they want to bring Bellerin back to his homeland to replace Trippier.
