"We want to win the group," Fergie said after the match.
"This result does no harm, of course. We didn't lose and the performance in the second half was the most encouraging thing.
"We deserved to get a point, but with minutes to go you think you are going to lose it, that it is not going to be your night.
"Losing the early goal set us back but that happens in football. It gave Celtic a boost and it gave the crowd a boost.
"You could say half-time came at a good time for us.
"We bring Berbatov on and it gave them another problem. The positions he picks up are very difficult to pinpoint.
"Also, the urgency of the team, knowing they were behind, came through."
