AFC Wimbledon boss Johnnie Jackson blamed their FA Cup first-round exit at Crewe Alexandra on a lack of "quality in decisive moments".

The Dons were beaten 2-1 with Charlie McNeill's strike from the halfway line putting the hosts in front. Crewe doubled their lead in the second half before the Dons scored a late consolation through right-back Andy Yiadom.

"It's obviously a bad result. We wanted to go through and we haven't done that," Jackson told BBC Radio London.

"It's a game that we should at least force to extra time. We had long enough spells where we were well on top, but didn't show enough quality in decisive moments.

"Probably the one bit of quality in the game is their opening goal. It gives them a leg up in the game and that ended up being a difference.

"We're out of the cup and obviously that stings."

Jackson felt his players should have prevented McNeill's 50-yard goal and was also frustrated by their inability to convert their own chances.

"Well played to the lad, it's a great bit of skill, well executed," he said of Crewe's opener.

"We should deal with the situation miles better. We forced them long from the goal kick and I expect my centre-halves to be able to deal with that situation, but we don't and it allows the lad the opportunity to see the keeper off the line.

"It's a great goal from his point of view. Wholly avoidable from ours.

"That's a moment of quality we didn't show. We've had 19 shots on goal, we've got to the final third numerous times and put a lot of crosses into the box.

"We need more to show for it than one goal."
