Foster expects to be the target of the boo boys given his Birmingham City connection.
He said: "I will get some (boos) to be fair but I'm used to that.
"We played each other three times last season and I was never on the losing side and hopefully I won't be come next week.
"We know it is going to be a tough match against Villa. They are coming off the back of a disappointing defeat against Man City and we are boosted by the big derby win against Wolves.
"We will go into the game full of confidence and if we get three points there, all of a sudden, it's a different story and we are in the top half of the table."
