Manchester City goalkeeper Joe Hart has no doubt Ben Foster will benefit from his move to Birmingham City.
Foster replaced Hart as Brum's No1 this season after deciding to leave Manchester United.
"The goalkeeping coach, I can't speak highly enough of Dave Watson," Hart told the Birmingham Mail.
"I worked closely with him. Every day means the world to him football-wise and he is going to do the same with Ben.
"He will really push him. Ben is a great 'keeper and it will be great for him to be a number one and you have seen in his early performances for Birmingham that he is going to do well."
