Defender Zat Knight believes Bolton have to rediscover their "horrible" side and make opponents fear them again.
Wanderers slipped to the bottom of the Barclays Premier League with a home defeat - their 12th of the season - against Aston Villa at the weekend.
Manager Owen Coyle publicly questioned the attitude of some of his players at the weekend and Knight accepts there are plenty of improvements to be made in all areas, telling the club's official website, www.bwfc.co.uk: "We have to do better all over the park - in defence, midfield and up front."
