"You don't expect to be picked for England when you are not playing, but I don't want to leave Manchester United,"Foster has told BBC Sport.
"Manchester United are the biggest club in the world.
"I know if I stay there, I will get my chance and I will be ready to take it. Anywhere else would be a step down.
"I can't complain about not being first choice for United. Edwin's done a fantastic job this season.
"I've got to wait until the summer comes and try to start again next season and give it my all."
