Chelsea manager Jose Mourinho has questioned midfielder Eden Hazard's commitment during matches.
Hazard, 23, claimed after the 3-1 defeat by Atletico Madrid on Wednesday that the Blues are set up to counter-attack and not to take the initiative.
"When the comments come from a player like Eden it's normal because he's not the kind of player to sacrifice himself for the team," said Mourinho.
"He's not mentally ready to look to his left-back and leave his life for him."
Mourinho added: "Normally you get these kind of comments from players like him, from players that can't resolve a problem like we had in the first goal.
"If you see the first goal of Atletico you completely understand where the mistake was and why we conceded that goal."
