Aston Villa boss Unai Emery insists they still have another gear in them.

Villa are sitting third after victory over Arsenal.

“I think we are increasing our level but we still have a lot of work to do," he said. “We have to build a team, increase our level and get better.

“When we played Nottingham Forest, Wolverhampton [Wanderers] and Bournemouth it was very difficult for us.

“We are going to face next week Brentford as well and I know it's going to be difficult – we have to respect them, trying to avoid their strengths and attack their weakness."
