Ridgewell hopes Foster signs permanently for West Brom
Foster is on-loan at Albion from Birmingham City.
"I sense Ben would like to stay here. I know him well and he is settled here and hopefully the club can keep him and Albion can sort it out.
"He is a Birmingham player but it is a different team to when he played there. I'm sure Ben would like to stay here and keep playing here because he is doing really well."
