The agent of Manchester United starlet Anthony Martial has derided Arsenal boss Arsene Wenger for being too slow to make a move for his client.

Martial's Old Trafford career has got off to an incredible start, with the 19-year-old scoring three goals in his first two Premier League appearances after signing from Monaco for £36million.

It is understood Wenger had been keeping tabs on Martial and had the opportunity to sign the Frenchman, but acted too slowly, allowing the Red Devils to swoop.

Martial's agent Philippe Lamboley told RMC Sport he could not understand Wenger's hesitation.

"Anthony is a true modern centre-forward who can change a side," Lamboley said.

"I am surprised by the analysis of Wenger, who has apparently been following him since he was a teenager.

"If Wenger made his analysis to justify not signing Anthony, then I accept his words and so he is a winger.

"But in football, there are those who follow footballers and those who buy them."
