Manchester United manager Sir Alex Ferguson has shrugged off Wayne Rooney
's temper tantrum in Turkey.
The champions' star striker reacted in anger to being substituted as Manchester United won their opening Champions League Group game against Besiktas in Istanbul.
A goal from Paul Scholes late in the game gave United, last season's beaten finalists, a 1-0 win on a night when they had to overcome a hostile atmosphere and cope with laser beams being shone in their eyes from the crowd.
Rooney briefly lost his temper when he was replaced in the second half, throwing his boots down and exchanging words with abusive Turkish fans behind the United dugout.
United manager Sir Alex Ferguson said: 'Wayne played as a lone striker for an hour and he was always coming off. He is never pleased to come off as he has that kind of energy. He wants to play all the time.
'TV mentioned to me an incident with the crowd but I never saw it. I did notice the laser and Jonny Evans was getting it all the time. But the police did something about it and got the man out at half-time.
'This was a good victory for us in a challenging atmosphere. I've never heard a noise as loud as this in a football ground. We showed great concentration and composure and, in the main, we have done well.'
Ferguson was also altered to a security problem behind his dug-out, although he was eager not to make an issue of that.
'Someone mentioned it to me, but I never saw anything,' he said. 'I do know the fans made the loudest noise I have ever heard. They never stopped the whole night.'
It didn't stop United opening their quest to reach a third successive Champions League final in the perfect manner.
Ferguson was delighted with his team's overall display, particularly Antonio Valencia, who was making his Champions League debut following his £17million summer arrival from Wigan.
'Antonio was always a threat,' said Ferguson. 'He got to the by-line so many times and really we should have done better.

Chelsea were also 1-0 winners, Nicolas Anelka's early second-half goal accounting for Porto at Stamford Bridge.
Skipper John Terry, who took a hefty blow from Bruno Alves early in the game, revealed: 'I was knocked out for about 10 seconds, but I'm fine now.'
