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."
