United finish off Group A with a home game against Shakhtar Donetsk, needing at least a point to keep the Ukrainians off top spot. For now, attention is focused on the Barclays Premier League and Sunday's noon showdown at Tottenham.
"Everybody was really chuffed," he told MUTV. "I think we were due a performance like that. For a large part of previous games, we have dominated but never really killed off a team. We did it here and take a lot of confidence from that.
"Defensively, we were sound and, going forward, we looked a threat as Shinji Kagawa, Antonio Valencia and Nani wreaked havoc. We just said: 'Go out and run at them' to our attacking players and they did that. For us to really demolish Bayer was pleasing.
"Luckily, we have got our last game at home and we are very confident going into that as, in Europe, we've been very strong all season. Nobody is really tired in the dressing room, the enthusiasm is really up and, if we can get a win on Sunday at Spurs, we can consider this a good seven days."
