Jonathyn Quinn netted for United but they slipped to defeat against AC Milan in their opening Torneo di Viareggio tie on Tuesday afternoon.
The Academy forward struck home in the final minute for Willie Donachie, Peter Beardsley and Dave Watson's side but, already trailing by two, it wasn't enough to claim anything from the match.
Earlier, Bryan Cristante had given Milan a dream start when he fired in an eighth-minute free-kick from 20 yards following a foul by Steven Logan.
The Italians had chances to extend their advantage further but had to wait until midway through the second period before they notched number two.
And it came in some style, with Alex Pedone latching onto Brandon Miele's headed clearance and sending a volley from the edge of the box flying past goalkeeper Jak Alnwick, who got a hand to the effort but was unable to keep it out.
The Magpies face Under 17 Congo on Thursday.
Newcastle United (4-2-3-1): Jak Alnwick; Alex Nicholson (Alex Kitchen 46), Remie Streete (Ryan McKinnon 78), Lubo Satka, Lee Desmond; Steven Logan, Brandon Miele; Greg Olley (Jamie Sterry 61), Jonathyn Quinn, Rolando Aarons; Tom Heardman (Macauley Booth 90)
