Chelsea took another step closer to the Premier League title by winning 2-1 at Stamford Bridge, where Eden Hazard netted two first-half goals.
However, Man City caused the Premier League leaders some problems, prompting Conte to replace defender Zouma and send on Nemanja Matic to link up with N’Golo Kante in midfield.
Conte explained: “It was only a tactical change. I think Kante played very well in the first half but we were suffering too much in the midfield and for this reason I preferred to pick Matic and reinforce our midfield.
“I think it was right, because in the second half we didn’t risk.”
