Asked about the reverse leg and PSG’s determination to progress in Europe, he added: "They were excellent. The crowd was up, it was a really big game for them and their fans when another big team comes in the Champions League.
"Since they've had the big investment, it is clear their aim is to win the Champions League so all that was factored in. But we can play a lot better, we know that.
"I thought they played really well but I thought the defence and goalie stood up when they had to and kept a clean sheet, which not many teams do in that stadium. We need to play better, there is no denying that.
"We have to be more front-footed, but we will need to rest, recover, and when we are back in training the game plan will be clear. Hopefully on Tuesday night we'll be talking when we're through to the quarter-finals.
"Of course, the stadium made a difference on Wednesday as their players reacted off their fans. More often than not on Champions League nights, our players do that, and we don't need to ask our fans to be at their best.
"It's a given and it's up to us to react off that and perform because it's not easy to get into the Champions League quarter-finals - especially the draw we've been given.
"It's not going to be easy but if we are at our best we believe we can beat any team. If we do that, we will be the ones in the last eight."
