Steele told the Manchester Evening News: "He was disappointed with the Arsenal goal, we all were, but then he makes a terrific save from Robin Van Persie just after half time. His concentration levels had to be really spot on at that point.
"A lot of international managers look for how goalkeepers recover from a mistake. Is he affected, does his game crumble?
"Ben proved against Arsenal that he won't crumble. He did the same at Wembley against Chelsea. People forget despite him not being happy with his display we would never have got to penalties but for his save from Didier Drogba just after their second goal.
"You need that concentration for England and ability to put errors out of your mind. I speak to England keeper coach Ray Clemence and he says you can win an England game 2-0 and only touch the ball a few times but those touches could be the most important you ever have.
"Ben needs to develop that side and at 26 that is what is coming now. We know he has the basic techniques of kicking, catching, punching he wouldn't be here if he didn't have that.
"But concentration and mistake management is key. The way Ben has gone about that has been a big plus for me. That is what you would be looking for at international level. You cannot let your head drop because you cannot afford it."
