He said: "We have a better team than the team I have left, Bolton. There is a lot of talent there. I already see some very good signs from the team and we're playing some good football.
"If there is anything that needs to improve I think we need to be focused a little bit more because the goal we conceded against Ajax â€“ we need to concentrate a bit more if we're going to make sure we don't concede goals like that during the season.
"But overall I will tell you, we can do something this season."
