Pablo Hernandez's opener for Los Che at Old Trafford was the Reds' first European concession of the season but, rather than dwell on the missed opportunity to set a competition record or bemoan the Carrick mistake which proved costly, the United manager preferred to focus on overcoming a tricky hurdle to top Group C.
"Michael knows better," Sir Alex told MUTV. "It's just one of these unfortunate things. I thought he had a terrific game apart from that. But it's always nice to get records. Until last week we went 29 games without losing, for instance, and eventually you're going to lose. Tonight we were going for six clean sheets and we didn't get it, but the important thing is winning the group is more important than a goal record.
"I think we should've won the game. We had a lot of chances. Berba could have scored another four or five tonight, but the goalkeeper made some great saves. The most important thing was coming first after a game which I thought was quite entertaining. It was a good quality match and I'm quite pleased."
