"We're trying to become better as a team," he said reporters. "On the pitch and off the pitch we are really close.
"On the pitch we are starting to become a horrible team to play against. We've got a great, compact unit there in the middle, we get after the ball and we win it.
"We talk about the 'five second fury' when we lose it - go get it back. We are starting to do those things."
Wayne Rooney struck the only goal of the game to seal the win and help England move three points clear at the summit of Group E.
