Sir Alex Ferguson praised matchwinner Cristiano Ronaldo after Manchester United edged past Lyon 1-0 at Old Trafford to clinch a place in the last eight of the Champions League.
The Portuguese took his season's tally to an amazing 30, with his strike enough to earn the Red Devils a 2-1 aggregate success against the French champions.
Afterwards, manager Ferguson said: "It may not be the best goal he has scored this season, but it may turn out to be one of the most important.
"He has scored 30 goals already this season and it is only the start of March. Potentially there are 16 or 17 games ahead of him so he could end up with an even higher score.
"For a wide player to do that is fantastic. It is a great contribution."
However, Ferguson admitted that his side's overall performance was far from perfect, adding: "We should have done more with the possession and the chances we had.
"Some nervousness came in because we didn't take the chances and kill the game and so we were on a knife edge.
"The more important part of it was that we were defending well, the back four were quick to advance on to their opponents and that made a big difference."
