Chelsea boss Jose Mourinho says he will not panic after his side's premature exit from the Champions League.
Chelsea were flat throughout the whole game despite the numerical advantage after Paris Saint-Germain striker Zlatan Ibrahimovic was sent off.
And Mourinho admits his players were not good enough.
"Our performance was not good enough," Mourinho said after the game.
"The opponent was stronger than us, they coped better with the pressure of the game.
"We tried to win but the moment they had 10 men we felt too much pressure.
"Paris St-Germain deserved it. When a team can't defend two corners and concedes two goals to corners they don't deserve to win.
"I told my players it is not after a bad match that I kick tables and doors, it is time to be calm and analyse as a team.
"They were aggressive, what we used to call 'clever' on the continent. In England, that is not accepted as clever.
"They did what they did, after the second goal there was no more game. Simulation of injuries, they stopped the game completely.
"It is the beauty of English football but in continental football the other teams are more prepared to cope with the mental side. I wouldn't say 'dirty', but the other side."
