The discussion will turn, immediately, to whom "Poch" can sign to improve the side, and the Argentine will already be devising strategies to upgrade certain positions.
Pochettino will love Jan Vertonghen, Kyle Walker, Sandro, Paulinho, Emmanuel Adebayor and Erik Lamela, but what of the rest?
Left-back is an area of critical need, with Danny Rose underwhelming and Benoit Assou-Ekotto of questionable quality. Centre-back has been riddled with injuries and age issues for a year, while Brad Friedel won't last forever as a back-up goalkeeper.
There are players who've been strongly linked away from the club too, and there may be some replacement work for the Argentine to do before he even gets started.
