Michael Carrick is delighted to have seen Robin van Persie settle so quickly at Manchester United and has reiterated his stance regarding England selection.
United acquired the Premier League's leading marksman from 2011/12 in a £24million swoop on arch-rivals Arsenal.
They knew that Van Persie would offer them considerable firepower, but were prepared to offer him time in which to find his feet before producing his best.
The Dutchman has, however, already netted his first goal at Old Trafford and claimed his first hat-trick, and Carrick is convinced that there is still more to come from the prolific 29-year-old.
"World-class players have got a presence," said the United midfielder.
"When the ball came to Robin for his first goal on Sunday (against Southampton), 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.
"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."
Meanwhile, Carrick has maintained that he is happy to be back in the England squad after ruling himself out of contention for a place in Roy Hodgson's plans for Euro 2012.
Speaking ahead of a 2014 World Cup qualifier against Moldova on Friday, he said: "I am not different or any more special than the rest of the lads.
"I don't need assurances or guarantees of any kind, just a fair chance. If I am playing well then I want to get a chance. If I'm not, then fair enough.
"Anyone who knows me knows my ego is not big enough to think I should be here and expect to play.
"That's the manager's choice. It's just up to me to stay in the squad for starters and then hopefully push to get a place in the team."
