Arjen Robben has issued a statement denying claims that he criticised Jose Mourinho's rotation policy.
The winger was quoted in Saturday's newspapers saying that rotation was "bad for a player's confidence".
But Robben told the club's website: "I completely deny making any critical comments attributed to me about the manager's selection policy."
On Friday Mourinho told Ricardo Carvalho he needed an IQ test for criticising the Chelsea manager.
Carvalho had spoken out after being left out of the Chelsea side at Wigan on the opening day of the season but received a stern dressing-down by Mourinho.
Perhaps fearful of the same treatment, Robben was quick to deny reports which quoted him as saying: "If you play two or three matches and one match is bad, you are immediately on the bench and that's not good.
"It's bad for a player's self-confidence because you can't get a rhythm.
"The problem now is that if you have a dip in form or play badly then you are immediately replaced."
Chelsea captain John Terry told BBC Radio Five Live that the competition for places was good for the team.
But he denied that players were constantly in fear of being dropped by Mourinho.
"I think it's great the opportunity we have got at the club. If you play one bad game, I know the manager, he is not going to just drop you like that," he said.
"He realises what you can do and you can't play well all the time, he realises that. Obviously if you're playing badly for two or three games, you're going to be out of the side.
"Then it's down to you to impress the manager and get back in the team."
Terry added that he felt the team was being targeted by the media because they were champions.
"It's just paper talk because we did so well last season we are the team to upset. Everyone wants to unsettle us a little bit," he said.
