Chelsea manager Jose Mourinho says his relationship with striker Diego Costa is still very solid.
The Spain international threw his training bib at the Portuguese after not being involved in Sunday's 0-0 draw away at Tottenham Hotspur.
But the 52-year-old says it is normal for a top player to be upset when not involved during the 90 minutes.
"For me his behaviour is normal. A top player on the bench will not be happy," Mourinho is quoted as saying by the BBC.
"If he wants to hurt me it would not be with a bib. I have a good relationship with him.
"I think Diego is very privileged. He is the last player to be on the bench. Everyone has been on the bench - the captain [John] Terry, [Branislav] Ivanovic, [Gary] Cahill, [Cesc] Fabregas, Pedro and player of the season [Eden] Hazard.
"Diego is privileged to have been kept in the team for all these matches and today we thought our best strategy was to play with this. I am happy with my decision and the players.
"[Today] Eden could play the 90 minutes and was so good and dangerous for us, I felt he could have scored a goal.
"Diego is physically fine, no problems. He works well, every day his mood is positive, he is the positive guy in the team.
"I do not expect to have a player on the bench jumping and shouting because he is not playing."
