Chelsea sacked Thomas Tuchel who brought him in for a fee in the region of £ 34m and are expected to change their style of play which might affect Koulibaly’s playing time.
Playing in a back three is obviously quite different from playing in a back four and at Selhurst Graham Potter elected to play Thiago Silva and record signing Wesley Fofana as the two central defenders.
Those two were flanked by Ben Chilwell and Reece James and they looked dynamic in their defensive and attacking phases.
When a new manager walks through the door, every player is given a clean slate to start and there is a feeling that everyone is fighting for his spot again at Chelsea.
Kalidou Koulibaly has failed to entirely convince in the five Premier League games he’s played so far and despite being left on the bench against Palace, he reveals he’s feeling settled at Chelsea and his family is feeling good.
He told CorSport: “I feel great at Chelsea, my family is perfectly integrated.
“I arrived at the right moment, I play with players who have won many trophies.
“It is up to me to show on the pitch that they can count on me, for now I am very happy and I hope to continue like this.”
Chelsea will now hope to build on their first win of under new manager Graham Potter and get a run going when they face AC Milan in the Champions League on Wednesday.
They lost their first game to Dinamo Zagreb and could only draw against RB Salzburg, making the Milan game a must win.
