United's first foray into the UEFA Youth League proved an entertaining affair as Nicky Butt's side overcame Bayer Leverkusen 4-3.
Despite the sending off of Paddy McNair, the home side earned three points through a late James Wilson penalty with Paul Scholes helping his former team-mate Butt out in his role of assisting with the Under-19 coaching on a match-by-match basis.
The Reds were quickly out of the blocks and raced into a two-goal lead inside the first 10 minutes. Oliver Schnitzler came out of his goal and failed to deal with McNair's through ball as it skipped off the greasy surface and Wilson pounced to convert a simple finish.
Moments later, Ben Pearson robbed Paterson Chato Nguendong and moved forward with menace, cutting inside to beat Schnitzler with the aid of a slight deflection. A smart save by Schnitzler at his near post thwarted Wilson as the hosts looked in complete control, only for Leverkusen to score twice inside a minute.
Chato Nguendong's cross allowed Benjamin Henrichs to fire against the woodwork and Marc Brasnic was first to the rebound to steer home. A slip by the otherwise impressive Nicholas Ioannou then granted Brasnic the opportunity to skip round Pierluigi Gollini to slip in the equaliser.
A breakaway raid should have given the lead to the Germans but Henrichs was unable to keep his shot down while, at the other end, Andreas Pereira forced a routine stop out of Schnitzler from a free-kick and Joe Rothwell fired over a glorious opening in first-half stoppage time from a James Weir cross.
The start of second half was more sedate with few clear-cut chances until Pereira fizzed a drive off target after approach play by Rothwell. An injury to Pearson seemed to unsettle the Reds' rhythm as he played on before being substituted and Leverkusen led for the first time when Maximillian Wagener latched onto a stray pass in midfield and
