Chelsea legend Ruud Gullit says the ball is now in Diego Costa's court if he is to earn a place back in Jose Mourinho's plans.
Mourinho dropped Costa for their stalemate with Tottenham.
Gullit wrote for BBC Sport: "Mourinho kept picking Costa when he was not scoring for weeks and weeks and also defended him when he behaved badly on the field.
"He was very loyal to his player but there was always going to be a time where he would say 'enough is enough' and leave him out, and it came at the weekend.
"When you do that and the player himself still thinks he has done enough to be picked, then you have a problem - that seemed to be what was happening with Costa's behaviour at White Hart Lane.
"But Mourinho is the manager and now Costa knows he will be tough with him too. What happens next is up to him, but if he is not playing well, then he will stay on the bench."
