Wayne Rooney among those to miss chances against PSVGetty

Manchester United captain Wayne Rooney has confessed his side must find more quality up front after a toothless 0-0 draw with PSV Eindhoven. Three points at Old Trafford would have sealed United's place in the knockout stages of the Champions League, but instead Louis van Gaal's side must wait until the final match away to Wolfsburg – a game they must win if they are to guarantee progression.

Rooney, Jesse Lingard and Anthony Martial were among the players who missed great opportunities to put their side ahead in the first half.

''No, we're not," the United captain said when asked if his team were ruthless enough. "I think we need to score more goals as a team. I feel we showed a lack of composure, which put ourselves under pressure a lot.

''It's a learning curve for us, but we can't go on saying it's a learning curve. We have to start turning these games into victories.''

Just two points separate Wolfsburg, United and PSV in Group B. Should Van Gaal's side fail to win in Germany in two weeks time and PSV beat CSKA at home in their final match, United will be consigned to third place and drop into the Europa League.

United's chances of progressing will be slim should they turn in a similar performance to Wednesday's but Chris Smalling believes his side can still join Europe's elite in the last 16.

When asked if United can win in Wolfsburg, the defender told BT Sport: "I think we can. Ever since the first result against PSV, we've turned things round [in the group].

"We can go there with hope because we've beaten Wolfsburg already, here at Old Trafford. But coming into the Champions League games, we saw it as probably the toughest one so we've given ourselves a lot of hard work to do."
