The 36-year-old is expected to sign in the next 24 hours as Darren Fletcher's replacement in central midfield.

Barry has spent the last four years at Everton, but is searching for first-team football after Ronald Koeman's summer spending spree made competition for places fiercer at Goodison Park.

Pulis has been looking for an experienced head to replace Fletcher in midfield after the Baggies captain departed for Stoke City.

Former Aston Villa midfielder Barry has 628 Premier League appearances under his belt, and needs to play just five more games to overtake Ryan Giggs at the top of the league's all-time appearance charts.

He missed Everton's opening day 1-0 victory over Stoke with an ankle knock, is expected to be fit in time for Albion's trip to Burnley this Saturday.
