Pochettino was relieved of his duties after 18 months in charge and has been swiftly replaced by former Lille and OGC Nice boss Christophe Galtier.
The 50-year-old was appointed PSG manager in January 2021 and won the Trophee des Champions and Coupe de France before adding the Ligue 1 title last term.
But failure in Europe, including a late capitulation against Real Madrid in the Champions League round of 16 last season saw Pochettino's future hanging by a thread.
Pochettino had a two-and-a-half year spell as a player at PSG and the Argentine has taken to social media to pay respects to his former side.
"I want to wish everyone at PSG the very best for the future – the owners, the board, the players, all the staff and the supporters," the ex-Tottenham boss wrote on Instagram, alongside several pictures of his tenure, capped with one of him in team colours from his days as a player with the club.
"To Nasser - I want to say thank you for giving me the opportunity to be part of the PSG family again. We enjoyed some amazing moments and big wins all together and, as a coaching staff, with every experience we always take learnings to advance our evolution for the future.
"We are proud to finish as league champions at a club that has meant so much to me and my family, from my time here as a player and a captain, and now as a coach."
