AFC Wimbledon handed out a lesson to Swansea's youth on Tuesday night after they put three goals past the Welsh side on home soil.
Andy Barcham scored for the second match in succession to give the Dons the lead in the first half before a double from Dominic Poleon rounded off proceedings in front of a crowd of 461.
The Swans, who due to the tournament's regulations, were allowed experienced first team players and had Marvin Emnes operating in attack and his early energy was evident but the Dons defence stood firm.
The home side created the first chance of the match and could have have gone ahead through Poleon who had two chances in quick succession but was unable to convert either of them with Swansea keeper Gerhard Tremmel saving well on both occasions.
But it was Neal Ardley's men who took the lead when Barcham latched on to a pass from Tyrone Barnett and hit a strike that had too much for Tremmel in the away goal and that was how it finished at he break.
As the second half started, AFC Wimbledon controlled possession and made that count when Poleon, who had just missed an earlier chance, tapped in after Dean Parrett's shot could only be parried by the Swans keeper and the Dons forward had a gift which doubled the lead.
Substitute David Fitzpatrick then broadcasted his skill when he set-up the third goal with a mazy run down the right flank. His pin point cross was met by Poleon who got his second goal of the night when he volley in and all but ended the contest with just over 20 minutes left to play.
Poleon could have completed his hat-trick but it wasn't meant to be as his driven shot went just wide. Nevertheless Ardley will hope that the positives from Tuesday's game can be carried into the weekend's home game against Chesterfield.
