They will be buoyed not only by a 3-1 Capital One Cup third-round victory over Nottingham Forest on Wednesday, but also by the fact Arsenal have won once in their last five fixtures. Wenger has been criticised for not adding defensive recruitments to his ranks over the course of the summer, with a number of injuries restricting the Frenchman’s options at the back. One player set to line up for the Gunners is England international Calum Chambers, who was moulded into a first-team footballer under Pochettino’s tutelage at St Mary’s. The 19-year-old was one of a number of players to depart Southampton in the wake of Pochettino’s appointment at Spurs but his former manager is backing him to be a success at his new club. “Calum is a great personality and has a great talent,” he added. “He deserves his moment now because one year ago at the start of pre-season at Southampton he was playing in the development squad and step by step he deserved to play and win his place in the first team. It is not only because he has talent he also has a great personality and character.” Wenger, 64, has been in charge of Arsenal for the past 18 seasons and is comfortably the longest-serving boss in the Barclays Premier League. Newcastle’s Alan Pardew is next on the list on four years, with Sam Allardyce third following three full seasons at Upton Park. Press Association Pochettino has only just taken the reins at Spurs and will manage his first derby against fiercest rivals Arsenal on Saturday. The Argentinian came up against Wenger during his time in charge at Southampton and holds the man who has delivered three league titles for the Gunners in high regard. “We have a good relationship,” he said. “We played against Arsenal (for Southampton) I have full respect for him, he is a great manager. An 18-year stay in charge is not easy. It’s a big gap with me in Tottenham. “Tottenham for me is a big job, it’s a dream to stay here like (him) or to have the time Arsene had in Arsenal. For this, I need to show my skill, I need to work hard, I need to get the results. “In football you never know, you need to work with passion that we have. We are positive in our job, in our skill, with the players. We try to arrive as far as possible.” Recording only Tottenham’s third win over Arsenal in the Premier League era would give Pochettino a great grounding for following the blueprint of Wenger’s longevity in one job. Spurs go into the game on the back of just one point from their last three league games, having started the new campaign with back-to-back London derby victories over West Ham and QPR. Tottenham head coach Mauricio Pochettino is dreaming of replicating Arsene Wenger’s success at Arsenal across the other side of north London.
