Our under-21s romped into the last-16 of the Bristol Street Motors Trophy thanks to four second-half goals in a 4-0 win over ten-man MK Dons at Stadium MK on Tuesday night.
Samy Chouchane's penalty shortly after half time gave Albion a deserved lead after Ruairi McConville was fouled in the box, before substitute Joe Knight doubled the visitors' lead with a cool finish with 20 minutes to play.
Dawson Devoy was sent off for the lacklustre League Two outfit late on and the visitors took full advantage as Ruairi McConville and substitute Sahil Bashir grabbed quickfire goals at the death.
Shannon Ruth's side will eagerly await to see who their next opponent is after one of their best performances of the season.
Albion had the first big opportunity when Brody Peart crashed a shot against the crossbar after Joshua Duffus had his shot blocked from ten yards out.
Duffus could have had a hat-trick inside the opening 25 minutes after he curled an effort just past the post and then his goalbound shot was cleared off the line following goalkeeper Michael Kelly's wayward pass.
The visitors, who had 58% possession and ten shots to one in the first half, were comfortably the better team and nearly went ahead before the break Chouchane's shot looped agonisingly onto the roof of the net.
The away side finally managed to get their noses in front when defender McConville was bundled over in the area and Tunisian Chouchane converted from 12 yards.
Jamie Mullins wasn't far away from doubling Albion's lead when he showed some neat footwork to jink away from two defenders, only to fire a shot straight at the keeper.
Milton Keynes finally showed signs of life after the hour mark when Tommy Smith powered a header at goal but Tom McGill did well to catch the effort on the goalline.
Substitute Knight then stroked a well-placed strike into the corner to give Albion a two-goal cushion in the 68th minute.
It was nearly 3-0 when substitute Marcus Ifill's drilled cross into the six-yard box was just diverted away from the fast-approaching Duffus and things got even worse for the hosts when Devoy was sent off for a last-man foul on Mullins 12 minutes from time.
McConville epitomised Albion's swagger when he ran 30 yards with the ball before finding the bottom corner from 15 yards out in the 89th minute and then substitute Bashir swept home in second-half stoppage time to compound Dons' misery mere seconds after coming on.
This was a statement victory for Albion who bounced back from their 3-0 Premier League 2 loss to Fulham on Friday.
