PSG looked fragile at the back, conceding twice from defensive lapses and showing some of the same issues that contributed to their 2-1 defeat by Bayern Munich in the previous round, but they responded with greater control and efficiency to turn the match around at the Parc des Princes.
Vitinha bagged a hattrick with two fine strikes and a penalty, while Pacho and Fabian Ruiz also scored for PSG, who were made to work after Tottenham twice led through Richarlison and Randal Kolo Muani, the France forward finishing with a double.
After four victories in five games, PSG, who finished with 10 men after Lucas Hernandez was sent off in stoppage time, are second in the league phase standings, on course for direct qualification to the last 16, while Tottenham are 16th on eight points.
