CHELSEA manager Jose Mourinho has questioned whether Kurt Zouma is really 19-years-old.
The big Frenchman signed for the Blues in January but as immediately loaned back to his club Saint-Etienne for the remainder of the season.
Zouma has been discussing his new life in London and explaining how he’s been settling in.
He said: “Diego Costa is very, very crazy. Ivanovic makes a lot of jokes too.
“Afterwards the group laugh a little about my age because, well, I’m a big man for 19-years-old.
