West Brom head coach Steve Clarke admits securing goalkeeper Ben Foster on a permanent basis was a top priority after the 29-year-old completed his permanent move from Birmingham on Friday.
Foster has made the switch from St Andrew's for an undisclosed fee after a successful loan spell at the Hawthorns last season.
The former Manchester United player has signed an initial three-year deal with a further two-year option in the club's favour.
"I think the supporters will be delighted we've been able to keep him on board and make him our player," Clarke said.
"In any league in the world you want a goalkeeper that is going to make match-winning saves, turn draws into wins and defeats into draws.
"A quality goalkeeper is worth 10 or 12 points a season to you - and that's certainly what we think we've got in Ben Foster."
Clarke admitted: "Ben's been a priority signing all summer. His performances last season were exceptional.
"It was important for the club to strike a permanent deal for him. It's a great signing for me and an even better one for the club."
Foster played a major role in helping Albion finish 10th in the Barclays Premier League last term.
He was named Albion's supporters' player of the Year and players' Player of the Year and kept 10 clean sheets, equalling the club record for the most shut-outs in a Premier League campaign.
Foster retired from international football with England just over a year ago to help him recover from a series of niggling injuries and ensure he was fully fit on a week-to-week basis.
But only a groin injury ahead of the final game of the season against Arsenal prevented him from playing all 38 league games for the second successive year.
Baggies sporting and technical director Dan Ashworth said: "The players, the staff and supporters will be delighted Ben has agreed to join us permanently.
"Ben showed to everyone last season how important he is to us, making vital saves at key moments in games.
"He was happy here, enjoyed the goalkeeper coaching under Dean Kiely, the facilities, the supporters, and everything about the club."
