Chelsea boss Carlo Ancelotti has warned Salomon Kalou he must fight for a starting place.
Kalou threw a wobbler after scoring the winner against Tottenham, having come off the bench to net his late goal.
Ancelotti has told Kalou - who has now scored 10 goals in 29 appearances in the league this term - he has some way to go before he can be considered first choice.
The Italian said: "I don't know if he was disappointed or not but it doesn't matter.
"I am happy because he scored a goal and if he didn't celebrate because he was disappointed, I am not interested.
"It is not a problem. I have to manage very professional players.
"I understand that sometimes they are not happy to stay on the bench but this is Chelsea, this is a top club and you have competition.
"A top club does not just have 11 players. We have fantastic players so sometimes it can happen that someone has to stay on the bench."
