New signing Romeo Lavia's ankle injury is a "sad situation", says Chelsea manager Mauricio Pochettino.

The 19-year-old limped out of training last week, prompting fears he could be out of action for a number of weeks.

The midfielder is yet to make his Chelsea debut since his summer arrival from Southampton in a £58m deal.

"It's a sad situation because he was nearly ready to be involved - Lavia was training well last week," said Pochettino.

"In the international break he twisted his ankle, so we are waiting for Monday to find out more."

It is the latest injury concern for the Argentine manager, who is without nine first-team players including club captain Reece James.

"He (James) is recovering well, I don't know if he is close or not," he added.

"We assess him every day and he has started doing things on the pitch with the ball.

"He is desperate to help the team. Hopefully, he can be available before the next international break.

"Armando Broja isn't ready to play just yet and it's the same for Benoit Badiashile."
