West Ham United sign Nottingham Forest winger Michail Antonio

West Ham United have signed winger Michail Antonio from Nottingham Forest for an undisclosed fee.

The 25-year-old, who joined Forest last summer from Sheffield Wednesday, scored 15 goals in 49 appearances for the club.

Antonio, who has signed a four-year contract at Upton Park, told the club's website: "I'm buzzing and finally happy to be back in London at a massive club.

"I've worked my way from non-league and finally got to the Premier League to show what I can do, and if the fans don't know me from the Championship, what I bring to the table is pace, power and goals, so hopefully I can do that this season.

"I can't wait for the challenge of playing in the Premier League. It was one of the things growing up, where I wanted to be, testing myself against the best competition and, seeing West Ham's result of winning 3-0 at Anfield, it shows I'm coming to a great team that's established in the Premier League. Hopefully I can put my mark down here at the club."

Antonio could make his Hammers debut at home to Newcastle United on September 14.
