United made it two wins out of two in Slovakia with a convincing 4-0 success against Dukla Banska Bystrica.
Although facing Dukla's B side, believed to be made up of Under-21 players, Paul McGuinness' youngsters turned on the style with two goals in each half.
Belgian prodigy Adnan Januzaj drew first blood from the penalty spot with Mats Daehli doubling the lead six minutes later from a Januzaj pass.
Half-time substitutes Kenji Gorre, with a header, and Jack Rudge also found the net after the break to cap an excellent performance with the Under-18 squad certain to have obtained plenty of experience from a rewarding trip.
United: J.Pereira; Grimshaw (McConnell 70), McNair (Evans 46), Dalley (Goss 70), Love; Pearson (Rudge 46), Weir (Willock 70), A.Pereira (Harrop 70), Daehli (Gorre 46), Januzaj; Wilson (Byrne 70).
