Manchester United's Reserves started the pre-season campaign with a 1-0 friendly defeat at Bray Wanderers.
Warren Joyce took a large squad to Ireland for the fixture and made 10 changes to the team at half time but saw Jake Kelly score the only goal of the game on 42 minutes.
Philly Hughes had an early header wide before the Reds made a impression with Bebe's shot blocked. Josh Harrop tested Stephen McGuinness with a couple of stinging efforts but Bray broke the deadlock when Kelly latched onto a pass by Ismahil Akinade to drill past Joel Castro Pereira.
Only captain Tom Thorpe kept his place for the second half and Joe Rothwell, Saidy Janko and Angelo Henriquez all mustered attempts as the Reds sought an equaliser. The closest Joyce's side came to restoring parity was when Tom Lawrence's fine drive produced an outstanding save out of Shane Redmond.
United: J.Pereira (O'Hara 46); Love (Janko 46), McConnell (McNair 46), Thorpe, C.Evans (Varela 46); Harrop (Rothwell 46), Goss (Petrucci 46), Pearson (A.Pereira 46), Willock (Lawrence 46), Bebe (Henriquez 46); A.Fletcher (Wilson 46).
