This comes after Bayern’s German Super Cup win over Borussia Dortmund on Wednesday night.
Joshua Kimmich struck in the 82nd minute at the Allianz Arena to give his side a 3-2 win as they defeated last season’s Bundesliga runners-up.
Corentin Tolisso and Muller had earlier put Bayern 2-0 in front, but Julian Brandt and Erling Haaland scored to bring Dortmund level in a tense affair.
But ultimately Kimmich’s goal gave Bayern the win and in the process meant Muller has picked up his record 27th trophy of his club career.
Thomas Muller won 27th trophy
The 31-year-old has won the Bundesliga nine times, the DFB-Pokal on six occasions, two Champions Leagues, one World Cup.
On top of that, he has one Club World Cup, two UEFA Super Cups and now six German Super Cups.
Muller picked up his 26th trophy just last week when Bayern defeated Sevilla 2-1 after extra time in the UEFA Super Cup.
He broke the record previously held by Bayern great Bastian Schweinsteiger less than a week later.
Muller who can play as an attacking midfielder, second striker, centre forward and on either wing joined Bayern Munich in 2008.
That win was surprisingly followed up by a 4-1 loss to Hoffenheim on Sunday in the Bundesliga, which snapped a 32-match unbeaten run for Bayern.
It has been a banner year for Bayern, who won the treble last season before picking up two trophies in the span of a week in the new 2020-21 campaign.
After his side’s exertions in Budapest in the UEFA Super Cup, head coach Hansi Flick said after the Hoffenheim defeat that he could hardly blame his side for being tired.
Bayern will now return to league action on Sunday when they face Hertha at the Allianz Arena.
