West Bromwich Albion have completed the £3.25 million signing of Scott Carson from Liverpool.

The 22-year-old England international goalkeeper, who played in 35 Premier League games for Aston Villa last season, has put pen to paper on a four-year-deal with the club having the option of adding another year to the deal.

West Brom's newly-promoted rivals Stoke City ruled themselves out of the running for Carson - who could cost the West Midlands club £3.75m depending on performance-related criteria.

His arrival takes Tony Mowbray's summer spending to an initial £13.75m after the signings of Roman Bednar, Luke Moore, Do-heon Kim, Graham Dorrans, Gianni Zuiverloon and Marek Cech.

Sven-Goran Eriksson named Carson in his 2006 World Cup squad and he made two B international appearances for England before being handed his senior debut in a 1-0 friendly win over Austria in November.

Five days later, with Paul Robinson out of form, he was thrown in at the deep end in a make-or-break Euro 2008 qualifier against Croatia - but his competitive debut ended in misery as England lost 3-2.

Carson joined Leeds United as a trainee in September 2002 after being spotted playing for non-league Workington Town in the FA Youth Cup. He made his Premier League debut for Leeds against Middlesbrough in January 2004.

And 12 months later, with West Brom tracking Carson, Liverpool beat off a host of clubs, including Chelsea, to snap him up in a £750,000 deal. However, his chances at Anfield were limited and a two-month spell at Sheffield Wednesday towards the end of the 2005-06 campaign was swiftly followed by a season-long loan at Charlton Athletic.
