Germany star Mario Goetze scored twice as he made his Bayern Munich debut on Sunday in the European champions' 4-1 friendly win at Hungary's FC Gyor.
Bayern opened the new Bundesliga season with a 3-1 win at home to Borussia Moenchengladbach on Friday, but Munich coach Pep Guardiola gave Goetze 30 minutes off the bench in a friendly at Hungarian champions Gyor.
The 21-year-old Goetze, who cost Bayern 37 million euros ($49.3 million) from rivals Borussia Dortmund, scored his first goal just two minutes after coming off the bench then added a second just before the final whistle.
He had five shots on goal in his 30 minutes and looked sharp 103 days after tearing his hamstring against Real Madrid in the Champions League semi-final as a Dortmund player.
"For a first appearance, it could have gone worse," said Goetze. "It was only a friendly, but for me it was something special."
Less than 48 hours after the Gladbach win, Guardiola included just Thomas Mueller from the starting line-up from Friday's Bundesliga opener.
Both Spain Under-21 captain Thiago Alcantara and Javi Martinez played for Bayern as Gyor took a 40th-minute lead with a well-taken goal from Leandro Martinez.
Bayern levelled through Swiss winger Xherdan Shaqiri on 58 minutes before Goetze came off the bench to give his side the lead after hitting the post, then drilling home the rebound.
Shaqiri added his second and Bayern's third before Goetze picked up a wayward back pass, dribbled around the defence and lobbed the goalkeeper just before the final whistle.
In a ZDF interview on Saturday, Goezte admitted he could understand the Dortmund fans' anger when he announced in April that he would join Bayern.
"I can completely understand the way they reacted, even if sometimes they over-stepped the mark," said Goetze with "traitor" one of the less offensive comments on his Facebook page after news of his transfer broke.
