United snatched a first-half lead last night through Cacapa, before two goals from Kazenga LuaLua and then Xisco's double sealed a fine win for the second string.
The night also saw a run-out for Alan Smith, who skippered the side and played the full 90 minutes as he continues his comeback from an ankle injury.
