The Manchester City players celebrated wildly in their dressing room after reaching the Champions League final on Tuesday night.
And a video posted by keeper Zack Steffen showed the players going mad after the match.
The footage shows the players collectively singing ‘It’s Friday Then Saturday sunday (What!)’ while bouncing up and down with joy.
The Man City boss has not reached a Champions League final since he won the trophy for a second time with Barcelona in 2011.
Guardiola’s record in finals is remarkable as he hasn’t lost one since he took Barcelona to the 2011 Spanish Cup final against Real Madrid.
