Ben Foster is on the verge of signing for Watford in a £2.5 million deal.

Foster, the former England goalkeeper, will complete his return to the Premier League later this week with a fee very close to being agreed with West Bromwich Albion.

The 35-year-old is ready to undergo a medical at Watford's training ground in the next few days, leaving Albion under a cloud after his refusal to join his team-mates at a training camp in Portugal last week.

Foster told Albion officials he did not want to join Darren Moore's squad amid the interest from Watford, with team-mate Craig Dawson also staying at home.

West Brom are already in talks over Foster's replacement and want Manchester United's Sam Johnstone, who has impressed on loan at Championship rivals Aston Villa.
