Austria coach Ralf Rangnick says Marcel Sabitzer has rediscovered his confidence at Manchester United.
Sabitzer struck twice in Austria's win against Azerbaijan.
Former United interim boss Rangnick suggested that the midfielder was playing with more confidence than he did while he was at Bayern Munich.
He said: "He has a lot more confidence than when he was at Bayern.
"Nobody dropped out in this game, but of course you can say that Sabi was the difference player after scoring two goals and preparing one."
Sabitzer is on-loan from Bayern Munich to the end of the season.
