Manchester City are in Paris tonight looking for victory at the Parc des Princes.
Guardiola's men defeated PSG en route to the club's first-ever Champions League final last season and are undefeated against the French outfit in their previous five encounters.
Much has changed in Paris since though.
A busy summer window saw Pochettino bolster his options with a series of Bosman buys in the form of Lionel Messi, Sergio Ramos, Georginio Wijnaldum and Gianluigi Donnarumma.
Elsewhere, close to £70m was invested in full-back Achraf Hakimi and defensive midfielder Danilo Perreira.

What is the early Man City vs PSG team news?
City are without Oleksandr Zinchenko and Ilkay Gundogan for the trip. Academy prospects James McAtee and Josh Wilson-Esbrand will be named among the 10-man bench.
For PSG, the big news is that Lionel Messi is expected to be fit enough to return to the squad.
Whether he will start, however, remains to be seen. Pochettino is also bolstered by the return of Marco Verratti.
Angel Di Maria and Sergio Ramos are both currently sidelined.
