That leaves question marks over the future of Baggies centre back Joleon Lescott, a player who has previously been linked with a switch to Aston Villa.
Tony Pulis is understood to have already agreed a £5million deal with Tottenham from the Argentine, despite the fact Spurs only signed him from Sevilla for £8 million last summer.
Fazio is keen on a move to the Hawthorns and the opportunity of regular first team football, so personal terms are not expected to be an issue.
The arrival of the 28-year-old is expected to increase speculation surrounding the future of Lescott, who was dropped for the Baggies goalless draw with Watford at the weekend.
Our resident Baggies fans here in the Transfer Tavern are not particularly enlightened by this news, with many of them not being very impressed with Fazio’s displays during his time at Spurs!
