Chelsea boss Luiz Felipe Scolari has admitted to having sleepless nights following the pressure which follows negative results.
Scolari skipped Saturday's post-match press conference following the Blues' 2-0 win at Bolton Wanderers and assistant first-team coach Ray Wilkins admitted the Brazilian coach was feeling a little tired.
But with Chelsea still not guaranteed of their place in the knockout stages of the Champions League and slipping off the top of the Premier League following a draw with Newcastle United and defeat to Arsenal in recent weeks, Scolari has admitted he is feeling the strain.
"When we lose or draw I feel it more than the players," he told the Evening Standard.
"I sleep very well before the game but when we lose I find it impossible to sleep afterwards because of the feeling.
"Sometimes I talk to my wife, sometimes I go to sleep in the other room because I change my position and my wife can't sleep.
"So I go there and watch TV until 3am in the morning with the feeling, 'Who is wrong? Is it me that was wrong or the players?' It is difficult.
"I never relax even if we win the game because I need to think, 'Okay, we won this game but for the next game they will play differently, they will play another system. We need to be in training tomorrow - who is injured and who is not?'
"I am thinking every day about the next day. It's difficult for the coach when you have so much competition."
