Manchester United manager Sir Alex Ferguson admitted that his side got lucky with a controversial penalty against Bolton.

Cristiano Ronaldo appeared to have been thwarted by a superb Jlloyd Samuel block but to the amazement of the away side, controversial referee Rob Styles lived up to his reputation by awarding the Red Devils an incredible penalty, one which Ronaldo duly converted.

Even Ferguson accepted Styles had got it wrong, although as the official has previously angered the United boss with his decision-making, he does not feel much sympathy.

"I was surprised because it looked as though their lad got a foot on the ball," said Ferguson.

"But Rob Styles turned us down four or five times last year so maybe it is payback time. But he still owes us another four."

Wayne Rooney's excellent finish 11 minutes from time doubled United's lead, the England striker's first goal of the season a perfect response to being left out of Ferguson's starting line-up.

"He made a difference when he came on," said Ferguson.

"If we are getting responses like that from players it is terrific for the club."

Ferguson confirmed Owen Hargreaves is likely to miss the Champions League encounter with Aalborg in Denmark on Tuesday with a knee injury, although Wes Brown, who also sat out Saturday's win, is expected to play.

That is of little consequence to Megson though, having seen an hour's worth of honest endeavour get no reward.

"I want to see the right decisions made," said Megson, whose side had the best chance up to that point when Fabrice Muamba fired wide from an excellent position.

"If TV replays take too long then we won't do them but from looking at other sports, TV can do these things.

"They talk about dropping the referee but what does that solve? It is just a symbolic gesture.

"Everybody knows what happened. Jlloyd Samuel won the ball. It is astonishing."
