Manchester United 0 Cluj 1: match report We qualified early and we qualified comfortably and we're now in the next stage as winners of the group, but we could face Shakthar Donetsk, teams like Porto, these are all the big names in there. United will have to raise their game in the knockout stages if they are to harbour realistic hopes of a third appearance in the final in five seasons, however. Real Madrid and AC Milan are also potential opponents, with Celtic also lying in wait, so the difficulties experienced by United in Group H - they have fallen behind in five of their six games - cannot continue in the spring. Cluj took full advantage of the uncertainty and inexperience in United's ranks, though, with David de Gea's goal being peppered by the visitors prior to Luis Alberto's goal, a 30-yard strike on 56 minutes. United, meanwhile, saw Danny Welbeck's header cleared off the line before Wayne Rooney's lob was tipped over the bar by goalkeeper Mario Felgueiras. Rooney, playing from the start in order to boost his fitness, struggled to influence the game from his position on the right flank, but Ferguson insisted that the England forward will benefit from his outing. "Wayne has got another 90 minutes behind him, he is close to full fitness and hopefully he will be approaching top form come Sunday," Ferguson said. Sunday will be a different kettle of fish altogether. But I think we've done what we've set out to do tonight. We've given young players game time and the other players have had more game time, players like Phil Jones and Chris Smalling. Unfortunately Thomas Cleverley has got a calf injury, we'll have to see what he's like, but the positive thing is that we were able to rest players ahead of Sunday.
