Chelsea boss Mauricio Pochettino admits they're seeking another striker signing.

A knee injury for Christopher Nkunku has ruled out the summer arrival until January.

Pochettino said today: "The window is still open and the club are working. We will inform when something happens.

"It is unlucky because we need help now in this area, but it is going to be when all the players are fit. We are looking for the right profile. That is the most important thing, and we are trying."

On Romelu Lukaku, he also said: "The situation hasn't changed. In football all can happen, we will see in the future but for now nothing has changed.

"The situation was clear when we arrived, a wish between the club and player to find a solution. At the moment, we are relaxed."
