The Hammers are desperate to bolster their frontline, having eyed an array of players this summer.

Interest in the likes of Arsenal’s Olivier Giroud and Manchester City’s Kelechi Iheanacho has since ended.

That has left Hernandez as Bilic’s No1 striker target to solve West Ham’s issues up front.

The Bayer Leverkusen star, who has a £13million buy-out clause in his contract, is open to returning to the Premier League.

And Chelsea have also been tracking the former Manchester United goalscorer.
