Aston Villa have agreed a fee with Rangers for Spanish defender Carlos Cuellar.
The 26-year-old will now discuss terms with Villa, whose bid has invoked a release clause in Cuellar's contract.
Rangers confirmed on Monday they had accepted a bid of £7.8m for the player who starred for the Gers in their run to last season's 2007/8 UEFA Cup Final.
Rangers signed Cuellar from Primera Liga side Osasuna in the summer of 2007.
Gers boss Walter Smith has expressed his disappointment at Cuellar's decision to leave.
He said: 'This has come as a surprise and I am disappointed. Carlos Cuellar has been a great player for the football club and inevitably there has been speculation about him playing in the Premiership.
'The club has received a substantial uplift in fee and we will now reinvest in the team.'
Cuellar is set to become Villa's sixth signing of the summer following Curtis Davies, Steve Sidwell, Luke Young, Nicky Shorey and Brad Friedel.
