After Andre Villas-Boas and Tim Sherwood both struggled to produce success at White Hart Lane, Tottenham chairman Daniel Levy decided to make Southampton's Mauricio Pochettino the club's new manager. The former Argentina international, who also managed Espanyol, enjoyed great success on the South Coast, guiding the Saints to an eighth place finish in just their second season back in the top flight.
Pochettino has since signed the likes of Michel Vorm, Eric Dier, Federico Fazio, Ben Davies and Benjamin Stambouli, and has guided Spurs to two wins, two draws and two defeats from the first six games of the Premier League season, leaving them in 12th place in the table.
Sunday's fixture sees Pochettino face off against his former club, as Southampton travel to North London in a bid to continue their outstanding start to the season. Pochettino's replacement, Ronald Koeman, has continued the Argentine's fine work at St. Mary's Stadium, winning four of their first six games - despite losing the likes of Calum Chambers, Dejan Lovren, Luke Shaw, Adam Lallana and Rickie Lambert in a summer of upheaval.
New signings like Fraser Forster, Ryan Bertrand, Dusan Tadic and Graziano Pelle have all impressed, and whilst the Saints will be brimming with confidence, Spurs midfielder Mousa Dembele is determined to end their fine run of results, which has also included defeating Arsenal away from home in the Capital One Cup, saying that the team can't get caught up in the situation of Pochettino facing his former club.
"Things like Mauricio coming up against his old club don't make a difference, we want to beat every team. In every game there is something special for someone but for the team and the club, we have to win every match," Dembele said.
"It was a good performance at Arsenal but this is a different game. Southampton will do everything to beat us at our place but we know this and we've got a good team who will do anything to win," the Belgian international added.
Last season's games between the two sides both ended in 3-2 wins for Spurs under Sherwood, and Pochettino will be hoping for a similar result when the teams meet once again on Sunday afternoon.
