United keeper Altay Bayindir watched on from the bench as his side made a dream start in Leipzig. Arda Guller's corner from the right caused chaos inside the Austria six-yard box and Merih Demiral capitalised to slam the ball high into the net.
The defender's goal, inside the opening minute, proved to be the only one of a frenetic first half, with referee Artur Dias happy to let the game flow. However, Ralf Rangnick's side were a whisker away from an equaliser when Christoph Baumgartner somehow failed to convert from close range.
