Chelsea star Christopher Nkunku is once again injured and unavailable for action.

The Frenchman has suffered a hamstring injury, which he picked up in the Carabao Cup final.

Nkunku, who came off the bench in the 1-0 loss to Liverpool at Wembley on Sunday, could barely make it through part of the second half and extra time before breaking down.

On Friday, Pochettino told reporters: “He suffered a problem in his hamstring and then we will see in a few weeks if he is available.

“Now he is doing recovery from Sunday.

“Unlucky, bad luck because to suffer again another injury is tough for a player that didn't play too much during the season and also came from the Bundesliga, from Germany, with some problems."
