Chelsea manager Jose Mourinho has once again come out and criticised his team after not being able to kill off the opposition and has admitted that it has become exhausting to watch.

Mourinho was speaking after their narrow 1-0 win over Swansea on Boxing Day thanks to an Eden Hazard goal, with the ‘Special One” heaping special praise on Swans goalkeeper Gerhard Tremmel.

"They kill me. Every game I'm tired in the end," Mourinho revealed.

 "At half-time we all should be relaxed with a comfortable result and we weren't and the first thing that happens in the second half was probably the biggest chance of the game.”

"After that we had a clear penalty, after that the goalkeeper made another fantastic save from (Frank) Lampard's shot, because the ball was going in the corner and had a deflection, “ the Blues boss added.

"But the time goes on, we don't score the second goal and you feel like the opponent now believes and the opponent is keen to risk a bit more and put in a second striker. In this moment you are a bit in trouble.”

"You don't score, you finish feeling you are going to concede. But the boys, they worked hard defensively and in the last part they looked comfortable in their control of the game.”

"Deserved victory, important victory, and today I can say that the biggest responsible for the lack of goals was their goalkeeper, because he made three or four big saves."
