Sir Alex Ferguson says a “world class” performance from Wayne Rooney was pivotal in United’s 3-1 win over Arsenal.
“Wayne was unbelievable. I think he was the key point for us in the sense Arsenal just couldn’t handle him,” praised the manager.
"He was world class today, there’s absolutely no doubt. Every time when the ball went forward up the pitch towards him, we were on the attack. He turned the defenders so many times, it was a really top performance."
Like chief executive David Gill, Sir Alex is determined to keep Rooney at Old Trafford – not that his future is even an issue for the United boss.
“The boy’s very happy at the club, I know that, we’ve always known that," said Sir Alex.
“He’s very popular among the players, he couldn’t be a better lad really. He’s a really down to earth boy. He’ll not change because that’s the way he is.
"It’s refreshing in this day and age when there are so many celebrity footballers earning a lot of money. A lot of people change with success but I’m pleased to say he hasn’t.
“I don’t know the situation (with Rooney’s new contract), I don’t involve myself in that but I’m sure David Gill’s working with Paul Stretford (Rooney’s representative).
"Hopefully something does happen.”
Chelsea manager Carlo Ancelotti has hailed Manchester United striker Wayne Rooney as the best player in the world.
Rooney scored his seventh goal in the past four league games on Saturday to help United crush hapless Portsmouth 5-0 at Old Trafford and return to the top of the Premier League.
Ancelotti's Chelsea can reclaim top spot if the beat Arsenal on Sunday and the Italian claims that the form of Rooney is preventing the Blues side from running away with the title.
Ancelotti said: "At this moment he is the best in the world.
"Manchester are using Rooney very well right now. He improves his quality with every game and I am surprised his level never drops. Instead he always improves his performance.
"It's not just good for United but also the national team. To have him in this condition is important for the World Cup.
"The whole United team has the experience to fight until the end of the season."
Rooney has scored 21 Premier League goals this season to make him the top marksman in the division.
