Chelsea signed Belgium international Romeo Lavia from Southampton last summer but the midfielder is yet to make his debut for the Blues due to a series of injuries.

The Blues paid £58million for the 19-year-old, beating Liverpool for his signature.

“Romeo Lavia will be fit in maybe one week or 10 days,” Pochettino told reporters on Friday.

That means the Belgium midfielder will miss the Carabao Cup quarter-final clash against Newcastle United at Stamford Bridge on Tuesday.

Lavia will make his Chelsea debut in the Christmas eve game against Wolves or against Crystal Palace on December 27.
