Guardiola said: "I've said many times recently, we have played well but always you can improve.
"Hopefully, we can improve and do better, otherwise there's no point being here.
"Everybody can improve, Kevin De Bruyne can improve and I can improve. Last season we dropped a lot of points at home in the Premier League but this season we've been scoring goals.
"That was the reason we could not fight until the end against Chelsea and Tottenham."
