"It's frustrating to create as many chances as we did in the first half - which has been one of our problems - and not capitalise on it," said Allardyce. “That's had a massive impact on the result today.
“We're left extremely disappointed by the fact that we've ended up losing the game when we've put ourselves in the position to win it, not only by scoring the first goal but also the amount of chances we created in the first half after that.
“I think the second half was about Burnley playing forward with Wood up front with Barnes, and us not coping with the more direct style of play they chose to use.
“That gave them the first goal, which put more pressure on us. I think we overrode that pressure to a certain degree and started to find our way back into the game but didn't produce anything like the quality we did in the first half, apart from Gylfi manufacturing an opening for himself which he would've normally scored.
“He didn't and then we decide not to deal with a corner correctly and allow a free header for Wood to pop it in and inflict a very disappointing defeat.
“Ashley Williams then gets himself sent off, so what started to be looking like quite a bright afternoon ended up very disappointing indeed.
“It's an away defeat we certainly could have avoided and had we done better in the first half in front of goal we'd have won it, I believe."
