Romelu Lukaku has said that he is joining "the biggest club in the world" as the Belgian closes in on a move to Manchester United.

On Saturday morning, United revealed that they had reached an agreement with Everton for the transfer of the 24-year-old, who is understood to have undergone a medical in Los Angeles on Saturday afternoon.

Neither Everton nor Man United have confirmed that the transfer has officially taken place, but Lukaku has revealed that the move is one small step away from completion.

"It's the biggest club in the world. It's a club that's hungry to win the league again, to be dominant in the world again and the sort of opportunity I always wanted since a child," Lukaku told ESPN. "When they came calling I didn't have to think twice. So I'm really delighted to hopefully be part of their history.

"Who would say no to the biggest club in the world? The best stadium in England, the best fans. It's a perfect opportunity. I always said I want to play for a team that's challenging for every trophy that there is.

"I think Manchester United wants to be the dominant force and if you look at the history it says enough. To become part of a club like them is something I really wanted and I'm thankful for the opportunity they gave me and now it's time to work harder than I ever did before and I'm willing to do it."

Lukaku, who scored 25 Premier League goals last season, was strongly linked with a return to Chelsea this summer, but the powerful forward will join close friend Paul Pogba at Old Trafford.
