Aston Villa boss Paul Lambert is convinced the confidence is returning to his players.
Lambert said: "I think the confidence we're getting from winning games is getting bigger and better.
"Some of the football we played was excellent. We have only been with the lads for a fortnight. It's another win away from home against a good side.
"And I was happy with the clean sheet because it breeds confidence with everybody.
"The lads were throwing their bodies in and defending really strongly."
