Foster started out with non-league Racing Club Warwick before joining Stoke City in 2001.
During his time with the Potters, he had loan spells with Bristol City, Kidderminster Harriers – where he made his Football League debut in 2004 – and Wrexham.
He won the Football League Trophy with Wrexham in 2005, where he was spotted by Sir Alex Ferguson, and that summer he completed a surprise £1m move to Old Trafford.
Ben was immediately sent out on loan to Championship club Watford, where he remained for two seasons – helping the Hornets reach the Premier League in his first year and winning the club’s Player of the Year award in his second.
With a season of top-flight football under his belt, he returned to Old Trafford and made his debut against Derby County in March 2008, where he made a number of key saves and kept a clean sheet.
He went on to appear for the club in the Champions League, but his high point was undoubtedly his man of the match performance in the 2009 League Cup Final against Tottenham, which United won 4-1 on penalties after Foster had kept a clean sheet in normal time.
With Edwin van der Sar injured, Ben started the following season in goal for United but unable to dislodge the Dutchman permanently, he joined Birmingham City in May 2010.
While Blues were relegated from the Premier League in 2010-11, Foster had further success in the League Cup Final, helping City to a shock 2-1 victory over Arsenal. He also ended the campaign as the club’s Player of the Season and Players’ Player of the Season.
He then joined top-flight West Brom on a season-long loan, keeping ten clean sheets which equalled a club Premier League record. Further Player of the Season accolades followed before he made the move permanent in the summer of 2012.
Forster made his England debut against Spain in 2007 and after five appearances he took a self-imposed break from the international scene, returning to the set-up in 2013.
He was a member of England's World Cup squad in Brazil, keeping a clean sheet against Costa Rica in the Three Lions' final group game and continued as a Premier League regular with The Baggies until a knee injury curtailed his progress in the 2014/15 season.He returned to first-team action in January 2016, reclaiming his place in the West Brom starting line-up, and went on to make 15 appearances before the season's end.
