All eyes will be on the 22 players on the pitch when Chelsea host Arsenal live on Sky Sports on Saturday, but what about the coaching staff?
Arsenal's backroom team will be without Arsene Wenger in the dugout as he continues to serve his touchline ban, but Antonio Conte will take his usual spot among his trusty lieutenants on Chelsea's bench.
From one of Conte's former team-mates to Arsenal's father and son kitmen, we take you through each side's line-up off the field…
Assistant first-team coach Angelo Alessio: Antonio Conte's former team-mate, midfielder Alessio won the UEFA Cup and Coppa Italia alongside Conte in Juventus' midfield. Alessio has managed Italian clubs Imolese, Massese and SPAL and worked as an assistant at Napoli. He first linked up with Conte in a coaching capacity at Siena, where they guided the club to promotion, and followed him to work with Juventus and the Italian national team.
Assistant first-team coach Steve Holland: Steve Holland has worked as a first team coach under Andre Villas-Boas, Roberto Di Matteo, Rafael Benitez, Jose Mourinho, Guus Hiddink and, now, Conte, since stepping up from his role as reserve team boss in 2011. Holland is set to become England's assistant manager on a full-time basis from the end of this season.
Head coach Antonio Conte: The former midfielder is in his 11th year in management having previously had spells in charge of Arezzo, Bari, Atlanta, Siena, Juventus and Italy's national team. The 47-year-old cuts an animated figure on the touchline and is unlikely to spend much of Saturday's encounter in his seat.
First-team fitness coach Paolo Bertelli: Another coach Conte has taken with him from Juventus and Italy, Bertelli has also worked under former Chelsea boss Claudio Ranieri at Fiorentina and Roma.
Doctor David Porter: A club doctor who previously worked in Chelsea's academy, Porter could recently be seen rushing onto the Stamford Bridge pitch to help treat Hull's Ryan Mason after he fractured his skull in a collision with Gary Cahill.
Physio Jon Fearn: Fearn is best known for going onto the field to attend to Eden Hazard alongside Eva Carneiro during Chelsea's 2-2 draw with Swansea at the start of last season, much to Jose Mourinho's displeasure. He has been with the club for seven years.
Not in the picture…
Assistant first-team coach Gianluca Conte: The younger brother of head coach Antonio works as a coach for the Blues. They were both young players at their home town club of Lecce, they studied together at the University of Foggia and Gianluca has worked as an analyst with his brother at Bari, Juventus and with the Italy national team.
Head of medical services Colin Lewin: Lewin replaced long-serving cousin Gary as head of Arsenal's medical department when he moved on to take up a role with England. Colin has almost two decades on Arsenal's backroom staff. This is his seventh as the head of their medical department.
Manager Arsene Wenger: The Frenchman was embroiled in a touchline confrontation with Jose Mourinho during one of his recent visits to Stamford Bridge, but this time he will watch from the stands as he serves the third game of his touchline ban. Wenger is in his 21st season as Gunners boss - making him the longest serving manager in all of Europe's top-five leagues.
Assistant manager Steve Bould: Former Arsenal defender Steve Bould was named as Arsene Wenger's assistant in 2012. After a successful playing career with the Gunners, Bould worked with the club's youngsters before he was promoted to replace Pat Rice as Wenger's No 2.
Kit manager Vic Akers: Islington-born Akers has worked at Arsenal since 1985, founding and managing Arsenal Ladies as well as looking after the men's first-team kit since shortly after Wenger's arrival in 1996.
Club doctor Gary O'Driscoll: A former doctor in the world of rugby, Gary O'Driscoll has worked with the Ireland national team and Lions side and remains a member of the RFU disciplinary panel. As club doctor at Arsenal, he now provides expertise for the first-team and academy.
Assistant kit manager Paul Akers: Son of Vic, Paul helps his father to prepare clothing and equipment for the Arsenal first-team.
