West Ham have completed the signing of forward Jarrod Bowen from Championship club Hull City in a £20m-plus deal.
The 23-year-old, who scored 16 goals this season for Hull, has signed a five-and-a-half-year contract at the London Stadium.
He scored 54 goals in 131 appearances in all competitions for the Tigers, who he joined from Hereford United in 2014.
"We are delighted to welcome Jarrod to West Ham. I think he could be a big success," said manager David Moyes.
"He's probably what you'd call a wide forward these days, or perhaps an old-fashioned inside-right. He has played a couple of games as a second centre forward or as a number 10.
"When you score goals like he does, and in the numbers he does, in the Championship, it will give you a great chance of scoring goals in the Premier League. We were attracted to the goals he has scored over the years; not just in one year, but over the last three years."
