Manchester United legend Sir Alex Ferguson is impressed by Arsenal youngster Alex Iwobi.

Ferguson dropped Iwobi's name while discussing this season's title contenders.

He told Kicker: "I think there's five potential candidates: Manchester City as favourites, Tottenham and Liverpool, but also Man United are still there if we get some consistency soon. Even when you are trailing by six, eight points, it's still possible to catch one or two teams.

"The rivalry and the experience of Guardiola and Mourinho makes for an exciting competition.

"And you shouldn't forget Arsenal. The team is more sturdy. They've got better and more aggressive. I'm impressed with the young boy Alex Iwobi."
