Chelsea manager Jose Mourinho has said that striker Diego Costa will start Sunday's crucial Premier League game against Manchester City at the Etihad Stadium.
Mourinho said earlier on in the week that Costa couldn't play two games a week after he was left out of the starting line-up for the Blues' 1-1 draw against Schalke in the Champions League.
Speaking at his press conference ahead of the clash with City, the Chelsea boss said: "Diego is not in the best condition but he will start the game.
"He plays this game but he can not play against Bolton [in the League Cup], it's as simple as that."
Costa has been in terrific form so far this season, scoring seven goals in four games helping Chelsea to a 100% start to their Premier League campaign.
Mourinho was quizzed about how he will handle Costa when Champions League games are followed with fixtures against the likes of Liverpool and Manchester United.
He added: "I know, clearly, that we have to try to protect him until he gets completely fit.
"Let's see his evolution and let's hope he goes in the right direction, and becomes available to play every game."
Ahead of Sunday's game, Mourinho played down the significance of the game between the two sides.
Many pundits believe that Chelsea and City will make up the top two in the Premier League this season, but Mourinho was keen to point out that three points is the prize on offer at this stage of the season.
"We don't play against them, we play against other 19 teams and for the title not just City. There are other teams in this race.
"Other clubs have exactly the same ambition."
