Milan recovered after a nightmare start once their top stars came on, but still lost 3-2 away to Hungarians ZTE.
It was a very shaky start in Hungary, going behind within a couple of minutes when a corner was only cleared as far as the edge of the box for a ferocious Ubochioma strike, but he was left completely undisturbed.
Gergenyi was denied only by the woodwork, while Junior Messias and Olivier Giroud saw chances cancelled out by last-ditch tackles.
Zalaegerszegi TE doubled their lead with an own goal and again were very poor on a set play, Brescianini nodding into his own net.
Moments later, Matyas Tajti was allowed to get away from Brescianini far too easily, unleashing a screamer into the far top corner from distance.
Fode Ballo-Toure was brought down for a penalty, which was converted by Giroud.
The France centre-forward should’ve had a second on the stroke of half-time set up by Messias, kept out by a desperate save.
Ante Rebic and Alessandro Florenzi also tested their defences before numerous substitutions to bring out the big guns on the hour mark.
Mike Maignan almost scored a bizarre own goal with a mis-kicked clearance, but Yacine Adli again made a real impact with his performance in midfield, setting up the goal for 3-2 with a smart run and pull-back for Rade Krunic’s control and strike from 10 yards.
