West Ham boss Slaven Bilic insists patience is the key for Italy international Simone Zaza.
The striker, who signed on loan from Juventus with a view to a permanent club-record £24m transfer next year, has yet to score for the Hammers.
He has struggled so much that reports in Italy have claimed the Hammers could cancel his loan deal and send him back to Turin.
“He is definitely a good player who came from a big club to a new country,” said Bilic. New players need time. If we go back and think about Bergkamp, who needed – I don’t know – a year?
“The problem now is, and it is quite common with even the best players from abroad, they need time. Plus he wasn’t a regular at Juventus and didn’t have match fitness. It takes time sometimes, and unfortunately we don’t have that time.”
