West Ham have submitted a new and improved bid of £12million for Nottingham Forest right-back Matty Cash, Football Insider can reveal.

The Premier League outfit are trying to beat AC Milan to the capture of the defender before the window shuts next week.

A West Ham source has told Football Insider that the club have upped their opening offer for Cash to £12m.

This comes after Football Insider reported that West Ham initially bid £10m for the Forest academy product.

The Hammers have identified Cash as their top target this month to replace Pablo Zabaleta.

The 34-year-old is out of contract at the end of the season and set to leave the London Stadium after three years.

Zabaleta has started the last three Hammers league matches as part of a five-man defence due to Ryan Fredericks’ absence due to injury.

But the ex-Man City star has no future at West Ham beyond this campaign and there are no plans to offer him a new deal.

Football Insider broke the news on Wednesday that Milan were plotting a shock late-window move for Cash after being impressed by his development this season.

Cash has taken his game to new heights under Sabri Lamouchi this season, starting 26 of Forest’s 28 league matches.

He is renowned as an attacking full-back, scoring twice and providing four assists from Championship matches alone this term.
