Manchester United boss Sir Alex Ferguson feels Wayne Rooney has some work to do before he can be put into the same bracket as Kaka, Ronaldo and Lionel Messi. But he has no doubts the Merseysider will get there eventually.
"It was a pretty remarkable feat to get that hat-trick (on his Champions League debut against Fenerbahce) and his progress has never disappointed us at any point since. When we signed him as a kid, we thought he would become a really top player. Without question he is going in that direction.
"He is blessed with some ingredients only great footballers have. He has a great determination and hunger to win every match and every training session. That will never change. Sometimes there is criticism about the amounts footballers get paid. But when you see the effort he puts in, he is worth every penny. He plays as if he means it. It is a wonderful thing to have."
Ferguson has warned his defence to watch Wolfsurg's twin strikers Edin Dzeko and Grafite. Remarking on their goalscoring feats of last season, he said: "Their two strikers scored 71 goals between them last season. That is an incredible total," said Ferguson.
"They are both big, powerful lads and we did look at Dzeko. He is a very clever player who takes up good positions. Wolfsburg haven't started the season that well but they have got to grips with their game and they are getting winning results."
United's 1-0 win in Besiktas in the first group game of their campaign puts them in an already strong position but Ferguson has warned his players to be not too self-assured.
"It is a great opportunity," he said. "We all think the same. If you can get to that 10 points quickly you can change your team and give younger players an opportunity. But you have to be careful. You don't want to be too cocky. You have still to win your games - and we have only played one. We did get a fantastic result in Turkey but we have to maintain our consistency and concentration in the important matches in front of us."
