West Ham have made an offer rising to £12m for Nottingham Forest right-back Matty Cash.

The Hammers have bid an initial £10m with £2m more in add-ons - but they face competition from AC Milan and Southampton, among other clubs.

The 22-year-old has had an impressive campaign for Sabri Lamouchi's Championship promotion-chasing side and been watched by several other Premier League clubs.

Cash is on a list of British full-back targets at the San Siro along with Wigan's Antonee Robinson and Hearts' Aaron Hickey.

Southampton are keen as they look to strengthen in both full-back positions this month, including looking at Tottenham's Kyle Walker-Peters, who is set to be let out on loan. Cash, who is a Forest academy graduate, fits the bill for the south-coast club as they look to restore their reputation for signing and developing young English talent.
