Bolton Wanderers boss Owen Coyle says keeping the club up is the toughest challenge he's faced.

Coyle was speaking before victory over Aston Villa.

"Absolutely. There is no doubt about that," he told the Bolton News.

"We're in the best league in the world and when huge uncontrollables go against you, of course it makes it more difficult.

"We accept the highs are very high but, equally, when it's difficult you have to understand what's involved in a game and how you see your way through it.

"I've been very fortunate in my management. I've had relative success whatever club I've been at . . . I took over Bolton Wanderers second bottom of the league and addressed that; we had a terrific transition last year with the football we played and the personnel we brought in."
