Bolton Wanderers boss Owen Coyle was disappointed with his players in defeat to West Bromwich Albion.
Coyle was unhappy with his side's second half display which leaves them in the bottom three.
He said: "We were terrific in the first half and squandered some good chances but we felt at half-time we had built a platform to achieve a positive result.
"West Brom, to their credit, got hold of the ball in the second half and did very well.
"My source of frustration is that we need to be performing better in the second half than what we did.
"In the second half we lost the individual battles and if you give West Brom time on the ball, they have got good players that can create chances.
"The goal was a great header from Shane Long but it was avoidable and when the ball comes into the box I expect my players to be winning those headers."
