29-year old Foster called time with the England national team in May 2011 to focus on club football and be with his family more and Clarke believes it has been a good move for his career.
"If you're looking at a top-line goalkeeper, every mistake is analysed. If you go with England, it's magnified 10 times," said the Baggies boss.
"Ben decided he'd rather spend time with his family than be put under that stress and strain and we respect that. For us as a club, it's good.
"Ben likes to be out of the limelight. He likes to go out, do his training and play as well as he can for Albion.
"He gets enough satisfaction from that to keep his career going forward."
