Wigan Athletic boss Roberto Martinez refused to blame the poor pitch for the drab goalless draw with near-neighbours and relegation rivals Bolton Wanderers on Wednesday night.
The Trotters had late chances to win the game as Matt Taylor went close on three separate occasions, although Wigan had chances of their own with Charles N'Zogbia only being denied by the woodwork.
A frustrated Martinez said after the stalemate:"It's the same pitch for both sides. We must adapt and be ourselves and not use it as an excuse.
"We got into some great positions but maybe we got a bit anxious at times. We need to show a little composure and arrogance when we get these chances.
"They were solid and trying to play through set-plays, and I thought we stood up to that very well.
"Charles N'Zogbia hitting the post was the break you need in games like this and I felt we deserved it. You could see again that every time Charles got on the ball he made something happen, and that is a key ingredient of being a good side.
"We have great competition for places all over the park, and that is why I am so pleased.
"The clean sheet was important because it would have been easy to lose concentration in those conditions with the state of the pitch and the weather.
"But we were superb at the back and the way we dealt with the set-plays was excellent."
