Chelsea boss Jose Mourinho says he has no explanation as to why his players were so poor in the first half of the game against Newcastle United.
The Blues needed a late comeback to take one point away from St. James' Park.
And although the Portuguese was happy with the second half reaction, he was very disappointed with how his team performed in the first 45 minutes.
"We were so poor, so bad in the first half," Mourinho told reporters.
"It is possible to win the game with a good period but when you don't play for 45 minutes it's very difficult.
"I told the players at half-time that I have no time to ask them why they were so bad. I want to try to understand because I don't accept it.
"I am not a magician. I tried my best for the team. At half-time I said I was sorry I only had three subs as I wanted to change six.
"You cannot say that I react negatively, I complain, I am a critic. I laugh about it.
"The second half was a positive but I have to think a lot about the negative first half.
"I am both relieved and disappointed. I have extreme feelings of the negative and the positive. It depends on the opposition team and the objective but normally I am not happy with a point.
"I put the first half down to awful individual performances and when you have so many, it is impossible for a team to be a team.
"The reason why we had so many individual bad performances is difficult to answer but it is the reason why the team was not there in the first half."
