PSG manager Mauricio Pochettino has admitted that his side lacked the required energy to stop Manchester City in the second half.
The French giants took an early lead in their Wednesday tie staged in Paris but succumbed in the second half where they were reduced to ten men and according to the Argentine, it was difficult to match their opponents in the second stage of the game.
"There were two different halves, we did well in the first half but it is difficult to eliminate a team like City. We deserved to be ahead but they were better than us and dominated the second half. The two goals were accidents, but they created more than us. It was one half for each team.
"It is difficult to explain why they were better but we were better in the first half. It was difficult to cope, their physical condition, they were more aggressive. We didn't show the energy you need. The red card could be yellow, could be red, it was an action. The second leg, in football you need to believe. They have the advantage," Pochettino said.
