Fergie: 'We Need Four Strikers'
Ruud van Nistelrooy returned after a five-match absence and grabbing the winner against West Ham at Old Trafford.
It was the Dutchman's 149th career strike for United and his 23rd of the season.
Sir Alex Ferguson: 'Ruud is the best in Europe at pulling off a defender and scoring a goal like he did tonight.
'The great thing is that it was Ruud's first game for a few weeks, he needed the game but he scored a most important goal for us.
'It was a vital goal for us and just the kind of response we wanted to see.
'Now, I have a job picking my team for a massive game at Bolton on Saturday, although that is what I am paid to do.
'When we were at our very best, we had four great strikers. It was one of the factors in us winning the treble. We had great players at the time and everyone did their job.
'We have Van Nistelrooy, Saha and Wayne Rooney and also Giuseppe Rossi. If we can do that again and get four strikers competing for the position and we can rotate them at the right moments, as we have done tonight, that has to be good for the club.'
