Paris Saint-Germain star Marco Verratti admits his side cannot be complacent against Manchester United.

The Parisians go to Old Trafford, where they won in the knockout rounds two seasons ago, needing a win.

United would be happy with a point, as it would all but guarantee them qualification to the knockout stages.

Verratti knows United are better away than at home this season, but hopes his team is fully concentrated on getting the job done.

"It's a final," he told a media conference.

"I think everyone is looking forward to playing this game. We will play in a big stadium, against a big team and against big players.

"It will be necessary to pass this step. We have everything to have a good match and it will be necessary to show it on the field by making individual and collective efforts. We will have to play at 150 per cent because they too must win.

"There is always pressure at a big club like PSG. All the matches are important. We have already lost two during the group stage and we must not lose a third. You have to be confident, give your all on the pitch and we'll see the result.

"In all games it's a little difficult at the moment, but it is the case for all the teams. We had a difficult time for a lot of reasons, but we have to forget all that.

"We don't want to find excuses. We have to win tomorrow. We will play against a great team and we have to go for this victory. For that, it will be necessary to be perfect on an individual and collective level."
