Neal Maupay saw his former manager Graham Potter swap for Chelsea.
The Everton forward believes Potter should need some time to make his mark at Stamford Bridge.
Maupay himself moved from Brighton to Everton this summer to play under former Chelsea manager Frank Lampard.
Maupay explains why Chelsea shouldn’t expect things to turn around immediately under Potter.
“He is a very good manager but he won’t change things overnight. He will need time,” Maupay told the Telegraph. “Last season we finished ninth. But the season before that we finished 16th and we were only safe about three games before the end of the season.
“Football changes. Just because we were struggling yesterday doesn’t mean that tomorrow won’t be good. At Brighton we had two tough seasons and the third one was the good one. To build takes time.”
