"It's great to see Ben. He is a consistent performer, someone I get on well with, when we train and to play against," said the 25 year old.
"It's good to have keepers like that around. There are three top quality keepers here plus Jack Butland and Jon Ruddy, and everywhere you look there is good talent.
"Is Foster good enough to push me? Yes, but I've felt that every time I've come away with England.
"My job when I was first involved was to really push hard. We all train like we are going to play and push each other and it's really good.
"If anyone of the three played, then we'd be in a strong position."
However, Hart will not give up his position easily.
He said: "I'm in that privileged spot at the moment. I didn't dream of this spot because I didn't think it would happen.
"I'm doing what I've always wanted to do, I love it, I'll keep working and training hard if there are no keepers or 1,000 keepers.
"That number one spot is one I want to keep and last summer (Euro 2012) was a real high point in my career.
"It was one of the best footballing things I've done. To play in a tournament like that is a dream."
