West Ham United co-chairman David Sullivan is convinced new signing Michail Antonio will prove Premier League class.

The former Nottingham Forest winger joined the Hammers on deadline day.

Sullivan told whufc.com: "We have paid a sizeable fee for Michail and believe he could become a star player for the Club over the next few years.

"He has got pace and power and his stats show he has an eye for goal with an impressive record wherever he has played.

"He scored 15 goals last season in the Championship and was voted player of the year at Forest which shows what the fans thought of him. He has already scored four goals this season as well.

"As well as scoring, Michail has been instrumental in setting up goals for his team-mates creating 15 assists last season and it would be fantastic if he could repeat that at West Ham.

"We hope like Aaron Cresswell, he can make an immediate impression in the top flight and repeat the form which saw him attract interest from a number of Clubs in this window."
