Chelsea, Conte:"Costa didn't play because he stopped training on Tuesday"

Chelsea got back on track after the loss to Tottenham by defeating Leicester in an Italian derby between Antonio Conte and Claudio Ranieri. After the match, the Blues manager was asked many questions on Diego Costa since there has been so much speculation about the striker:"He stopped in training because he felt a pain in his back. He hasn't trained since then. This is the reason. I've read a lot of speculation. If there are problems I prefer to solve them in the dressing room, not a press conference. It's important to understand Costa's phsycal condition. Then we'll see if he can train with us"
