He told ESPN: "His shot-stopping, decision-making and presence have been solid all season. That is why there has been so much talk about him.
"I feel very lucky to be here and to have the chance to come in and train a couple of days a week. That's helping me feel part of the team."We felt it [going back to Birmingham] was the right thing to continue my development. It works out well for all sides and was the sensible option."
Butland was disappointed to see his parent club fall to a last minute defeat at Newcastle last weekend, but was quick to stress his faith in Pulis' charges to bounce back and ensure their place in the top flight.
He added: "I felt for them when I heard the result. It was just unfortunate to concede so late on.
"The lads have been fantastic defensively this year and they will put what happened to the back of their minds."
