Arsenal legend Thierry Henry has no doubts Manchester United winger Anthony Martial has world class potential.

Martial has already racked up five goals and six assists in his first nine appearances of the season for Jose Mourinho's side.

Henry, who scored 175 goals during his eight-year stay at Arsenal, believes Martial has shown enough to suggest he can reach the very top of the game.

"Anthony Martial is a far better player than I was at that age," said Henry.

"He can become a world class player."
