Boss Jose Mourinho might decide to make a move for former Chelsea striker Romelu Lukaku after the Belgian admitted that he is still a fan of the club.
The 22-year-old struggled to impose himself at Stamford Bridge after joining from Anderlecht but has since become one of the most prolific strikers of the English Premier League.
And according to Sport/Voetbal magazine, he still loves Chelsea.
"I will always be a fan of that club," he said.
"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."
