The Ivory Coast striker is “furious and upset” following the sacking of Mourinho.
A pal told The Sun: “Didier is absolutely furious with Chelsea and cannot believe they would sack Mourinho like this.
“He looked on Jose as his mentor and does not know that he can achieve his best form for Chelsea under another coach.
“It will take a few weeks yet before he’s fit to play but it’s a matter of when and not if that he’ll leave the club.”
