Southampton's players will not be leaving the club in the January transfer window, new chairman Katharina Liebherr has said.
The announcement follows speculation that some of the Saints' squad may depart in the wake of the resignation of previous chairman Nicola Cortese.
"The club has no plans to sell any of the squad during the January transfer window," said owner Liebherr.
"The manager and the team have my full support."
Cortese, 45, left Saints on Wednesday, with Liebherr becoming non-executive chairman.
Pochettino, 41, has been in charge of the Premier League club for just under a year, taking over from the sacked Nigel Adkins on 18 January 2013, having been brought to England by Cortese.
Luke Shaw, Adam Lallana and Rickie Lambert have all been linked with transfers this January prior to Cortese's exit.
"It's hard to predict what is going to be the effect on the players," Pochettino admitted. "It's clear that it may affect the players as they all have varying degrees of relationship with Nicola Cortese, and of course his leaving may affect us in some way."
