The France international suffered cruciate knee ligament damage during a 1-1 Premier League draw with Manchester United on Feb. 7.
It has been a long road back to fitness for the 21-year-old, who had nailed down a regular role in the Blues’ starting lineup prior to picking up an unfortunate injury – one which also dashed his Euro 2016 dreams.
Zouma was able to return to training over the summer, allowing him to make an early impression on incoming manager Antonio Conte.
He has, however, been eased into the fold, with an Under-23 outing against Derby County on Monday the first competitive action he has seen in the 2016-17 campaign.
