After James Wilson capped a fine second-half display for the team with a headed equaliser, it looked like being an excellent first excursion into foreign fields in the competition. But a sloppy late goal was conceded to Mykyta Bezuglyy to leave the Reds with three points from two games.
Scholes, who is assisting Nicky Butt with coaching the Under-19s, hinted that the teenagers should have been satisfied with a hard-earned point rather than pushing for a winner and getting caught out.
"The first half was disappointing and a struggle as we did not play as well as we'd have liked," Scholes told MUTV. "But we really stepped up and, once we got the goal, it looked like there was only one winner. It didn't turn out that way and the kids have to learn that if they make silly mistakes, they are going to give goals away.
"Nicky's message at half-time was he wanted the team to play like Manchester United - to pass, run and move. We didn't feel we passed the ball quickly enough in the first half or were running hard enough. We were not doing the things you expect from Manchester United but showed more intensity in our play in the second half and looked the only team likely to win it at one point."
After Wilson's leveller, the Reds made a valiant attempt to complete a fine turnaround despite the fact that 1-1 would have been a creditable result, as was the case with the first team later in the day.
"That's what the club is always about," Scholes admitted when asked about going for the three points. "From senior players to the young kids, now they've seen that growing up.
