West Ham United have completed a deal to sign Gianluca Scamacca from Sassuolo.

The Hammers have paid an initial £30.5million and an additional £5m in add-ons to sign the Italy striker.

Scamacca, 23, finished second in the Serie A top goalscorers list last season and has now signed a long-term contract with West Ham.

He will wear the number seven jersey for his new club.

"We've been looking to add more strength to our attacking options for a while, so we're delighted to have got Gianluca in," Moyes said after the signing was confirmed.

"He comes really well recommended – and we're looking forward to working with him.

"He's a young centre-forward with a really bright future ahead of him."
