Robin van Persie has given Manchester United an extra dimension with his "world class" finishing, Old Trafford team-mate Michael Carrick has said.
Van Persie, 29, joined United from Arsenal last month after a summer of speculation that had also seen him linked with Premier league champions Manchester City and Juventus.
After getting off the mark in United's second game against Fulham, Van Persie hit a hat-trick in the dramatic 3-2 win at Southampton on Sunday.
"World-class players have got a presence," Carrick explained. "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 scored 30 Premier League goals for Arsenal last season, winning the Golden Boot, and Carrick believes he has started life in Manchester in a way that promises a repeat of that feat.
"If Robin carries on like this, I will enjoy it very much,'' he said. "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."
