The French centre-half has been ruled out for a number of months after suffering the problem during the 1-1 draw with Manchester United in the Premier League at Stamford Bridge on 7 February.
Zouma underwent surgery to correct the problem in Barcelona earlier this month and is now back in London to continue his rehabilitation.

Zouma shared the picture above on his personal Instagram account and wrote: “Step by step… have a great day all ! #CFCfamily#hamdulilah”
