Andy Awford was was left frustrated after a late Burton leveller denied victory.
The Blues were heading for a first win in seven matches courtesy of Jed Wallace’s 37th-minute opener.
Yet in the 83 minute, Darragh Lenihan produced a classy finish from outside the box to secure a point for Jimmy Floyd Hasselbaink’s side.
It was heartbreak for the Blues, who now lie just three points above the League Two relegation zone.
And Awford felt they deserved to have picked up a win.
He said: ‘You get to the 83rd minute and you’d hope to win the game.
‘We hadn’t been in front for a while and I thought the performance level was excellent again, while I am a little bit frustrated we didn’t take all three.
‘We created that many chances against the team second in the league I think we were deservedly in the lead at half-time, but it probably should have been more at half-time.
‘That was the disappointing thing, we maybe should have had a two or three-goal cushion.
‘Burton are a good side, you know they are going to come at you, they had a good spell which we rode out and I thought we were going to run out winners – then they levelled.’
