Last night, in the 1-0 win over Borussia Dortmund, the Canadian registered a ridiculous 21.9mph when he raced back into catch Erling Haaland when the Norwegian forward was through on goal.
The former Vancouver Whitecaps starlet was in the opposition half when Haaland picked up the ball and danced past David Alaba, but turned on the jets and made a remarkable recovery.
His latest display of speed brought about a whole lot of reaction, including Inter Milan striker Romelu Lukaku, who wrote: "Alphonso Davies is fast as f***".
But it was his teammate Muller who had the best response of all. The World Cup winner compared his colleague to rapid cartoon character roadrunner and even did a hilarious impression.
Skip to around 1:34 for Muller's hilarity.
Muller said in a post-match interview: "He's a player with a lot of heart and a lot of power... extreme power.
"Sometimes maybe his positioning on the field is not the best, but he gets the opponent thinking, 'Oh, I have time, I have time'.
"And then 'Meep meep meep meep' the FC Bayern roadrunner comes ahead and steals the ball."
19-year old Davies has quickly established himself as Bayern's first-choice left-back since making the switch from the MLS and has produced an array of all-action displays up and down the flank.
He was sensational at Stamford Bridge in the 3-0 win over Chelsea in February, producing a stunning run and assist for Robert Lewandowski.
Davies is the real deal and he's absolutely rapid.
