Romelu Lukaku has emerged as a shock summer target for Manchester United, the Daily Star reports.
The 22-year-old is one of the main targets identified by Chelsea boss Jose Mourinho to take over from Didier Drogba.
But the Red Devils are reportedly ready to enter the race to sign the Belgium international.
Speaking at the start of the month about his future, the striker told Sport/Voetbal: "I will always be a fan of that club [Chelsea].
"Just because I left under the wrong circumstances, that feeling does not disappear. People will ask why, if that is the case, I left? But a footballer wants to play.
"After they won the title I sent a message [to fellow Belgian] Eden Hazard, just like I do every game when he scores or gives an assist. I knew what they were capable of this season.
"When they took Fabregas and Diego Costa, I knew right away: 'My God, this is going to create sparks'.
"Right from the start, even in the friendly match against Vitesse Arnhem and the difficult games against teams like Burnley who were fighting relegation, Chelsea played totally different than the season before.
"That was the true stuff of champions. I want to play football and that is the football that you have to play."
