Chelsea fear midfielder Reuben Loftus-Cheek might be sidelined for long after he suffered an injury during the club's friendly match against New England Revolution on Thursday morning. 

Loftus-Cheek was stretched off assisted by two Chelsea medical officers in the 68th minute and is now a doubt for the Europa League final against Arsenal on May 29. 

Marcos Alonso provided an insight into the Englishman's injury, which will be a worry for the club as they prepare for the final. 

“It doesn’t look very good, to be honest. Fingers crossed, it will not be too much and that he can be running as soon as possible," he said while talking to the media after the match. 

He added: “I think it’s his Achilles. I don’t know if he felt (it happened when) he was on his own. We are all very sad about this. It was very, very important not to get any injuries in this kind of game. Hopefully, it won’t be too bad,"

His injury is a big blow for the club, who have already lost Callum Hudson-Odoi to a similar injury and there are doubts over Ngolo Kante's fitness since he is still recovering from injury. 

Loftus-Cheek has been one of the best central midfielders for the club as demonstrated with his 10 goals including one in the Euefa Europa League semifinals.
