Poch is back.
The Argentine tactician signed a contract through June 2022 at the Parc des Princes, with an option for an additional year. Pochettino captained PSG during his playing career.
"I have wonderful memories, especially of the unique atmosphere of the Parc des Princes," Pochettino told the club website. "I return to the club today with a lot of ambition and humility, and am eager to work with some of the world's most talented players."
Tottenham Hotspur dismissed Pochettino in November 2019. The 48-year-old led the north London club to the Champions League final just 171 days before his sacking but paid the price for a disappointing start to the 2019-20 season. Spurs were positioned 14th in the Premier League table and were humiliated by a 7-2 home defeat to Bayern Munich in the Champions League group stage.
However, through his time in the English capital, he established Spurs among the Premier League's elite and was widely credited for his attacking, high-pressing style of play. His holistic approach also drew praise during his previous stints in charge of Espanyol (2009-2012) and Southampton (2013-2014).
He is yet to collect a trophy in his managerial career.
Pochettino's first match in the PSG dugout will be Wednesday's Ligue 1 trip to Saint-Etienne. His Champions League return is set for Feb. 16, when PSG travel to Barcelona for the first leg of the teams' last-16 tilt.
