Chelsea defender Toni Rudiger believes there's greater improvement inside the squad.

Rudiger insists the best is still to come from Chelsea even though they have won their first five League games to sit top of the Premier League.

He said: “There is always room for improvement. The coach has only been here for a few months so we will improve, definitely.

“The squad is strong enough to win the title, but it depends all on us because last season we dropped a lot of points against the smaller teams. We have to focus on every match.

“We cannot look ahead too far because we have just played a few matches. We have to go step by step and just try to win the next game.

“I can speak for the others, everyone is happy (with Maurizio Sarri). I like him as a coach. I knew him before from Italy, but I only played against him (for Roma).

“His last team Napoli always played good football. He is a funny guy off the pitch but on it he is serious about his work. That is good."
