West Ham chief David Sullivan says Simone Zaza can be a major Premier League star.

Zaza joined the Hammers from Juventus this week.

Sullivan explained on whufc.com: "This has been a big few days for the Club following the signing of Simone Zaza from Juventus over the weekend.

"Zaza could become one of the major stars and we saw his qualities when he came on and scored at London Stadium a few weeks ago.

"He's fit and ready to play. We expect him to lead the line against Watford."
