The father of Simone Zaza admits his son made a massive mistake by joining West Ham last summer, blaming the British weather and Slaven Bilic's tactics for the striker's miserable stay.

The Italian international joined the Hammers last summer on a season-long loan from Juventus following Euro 2016, where he found infamy for his awful penalty miss against Germany in the quarter-finals.

His fortunes in London were no better, as he played 11 times in all competitions under Bilic, failing to register a single goal before his short-term deal was terminated in January 2017.

He spent the second half of the season on loan at Valencia, which has now been made permanent following an impressive return to form, and his father Antonio, who also works as the striker's agent, believes a break from the miserable London forecast and Bilic has worked wonders for his son.
'It was a huge mistake,' Antonio told Calcio Mercato when asked about his move to the London Stadium.

'Simone was still concerned by the penalty he missed with Italy at the time and he failed to settle in well in London.
