Manchester United midfielder Michael Carrick is convinced Robin van Persie will bring the best out of the club.
The £24million Dutchman has already had an impact at Old Trafford, scoring on his home debut against Fulham before firing home the hat-trick that allowed his new club to register a comeback at Southampton on Sunday.
That victory allowed United to keep tabs on early pace-setters Chelsea and Carrick is convinced there is far more to come, especially now they have Van Persie's class to rely on.
"World-class players have got a presence," said Carrick.
"When the ball came to Robin for his first goal on Sunday, I was so confident it was going to be a goal.
"To have someone like that in your team is satisfying because you know if you supply him with the right ammunition, more often than not, he will put it away."
Van Persie collected the Golden Boot last season with his 30 Premier League goals for Arsenal.
And with four already for United this season, the 29-year-old is already well ahead of schedule.
It was the middle of October before he reached that figure last term, although from that point Van Persie did find the net an incredible 20 times in 17 games, emphasising the high standards he has set for himself.
Question marks have been raised over the impact Wayne Rooney is likely to have, especially as Shinji Kagawa has made such an impressive start to his own United career.
The options for manager Sir Alex Ferguson are huge, which Carrick believes will only be of benefit as the season progresses.
"If Robin carries on like this I will enjoy it very much," said the United midfielder.
"To get off the mark with pretty much his first touch was special, then his hat-trick was much needed because we were in a tough position.
"It's a better start than he could have hoped for.
"We have got some firepower at the club now and whoever the manager calls upon, we will look dangerous."
