Jose Mourinho said he reacted to Tottenham's midweek defeat at Manchester United by sleeping at the club's training ground.
Mourinho's 100 percent record since taking over at Spurs came to an end in a 2-1 loss against his former club at Old Trafford.
However, he said he refused to wallow in pity and instead started planning for Saturday's home game against Burnley.
"I slept in here (the training ground), I stayed here, I didn't go home, so the next morning at eight o'clock I was here doing what? Burnley," Mourinho explained on Friday.
"Analysing Burnley, trying to organise the training session, trying to organise the meeting, choosing the clips to show them the most clear possible way Burnley works.
"That's the way you have to do it in football. Don't accept in a passive way."
