Coach Antonio Conte has overseen two successive titles for the Old Lady, but did not see the surprise celebration waiting for him when the players returned to the changing room.
Conte was carried to an ice bath inside the dressing room after being unceremoniously stripped and then dumped in the freezing cold water in just his underwear.
Midfielder Arturo Vidal secured the win for Juventus over Palermo with a 59th-minute penalty after Mirko Vucinic was pushed by Massimo Donati.
And the players celebrated with placards bearing the legend "31" after the Italian authorities stripped the Turin club of their 2005 and 2006 championships following a match-fixing scandal (Daily Mail).
However, the players were unable to complete a lap of honour at the Juventus Stadium due to a pitch invasion by the supporters (Reuters).
Instead, though, Conte found himself as the centre of the indoor celebrations with his impromptu swimming lesson.
The title triumph, however, was marred a little by Pogba's dismissal seven minutes from the end of the Serie A match.
