Ben Foster heads back to St Andrew's on Saturday having enhanced his reputation as one of the best English goalkeepers of his generation, with several former Hornets teammates hailing him as the best they have worked with.
Foster made quite the impression at Birmingham in his one season there in 2010/11, winning the Player of the Season award, the Players' Player of the Season gong as well as the Alan Hardaker Trophy for the second time in his career for his man-of-the-match performance in the Blues' stunning League Cup final win over Arsenal.
He has since burnished his standing during a seven-year stint at West Bromwich Albion and now in two-and-a-bit seasons at Watford. At 37, his power shows no sign of waning and, if anything, he is getting better with age.
“He's the most natural goalkeeper I've ever worked with,” said club legend and one-time mentor Alec Chamberlain during a half-time appearance at Vicarage Road on Saturday. “He's learnt so much in terms of professionalism and his body shape and he's a very fit boy. He's looked after his knees and I just wish he hadn't retired from international football when he did.”
