Chelsea are chasing Atletico Madrid winger Yannick Carrasco.
Don Balon says Chelsea are interested the 23-year-old winger as are both Manchester United and Manchester City, Bayern Munich and Juventus.
Carrasco signed a new Atletico deal in October and is under contract with the club until 2022.
He also has a £86m buyout clause in his current deal.
But Chelsea would have such funds at their disposal at the end of the season and could launch a hefty offer for the Belgium international.
Should he make the move to Chelsea this summer, he would link up with several of his international team-mates at Stamford Bridge.
The Blues currently have Belgian trio Eden Hazard, Thibaut Courtois and Michy Batshuayi in their ranks.
