Two new London managers go head to head on Saturday as Maurizio Sarri's Chelsea host Unai Emery's Arsenal at Stamford Bridge.
Both clubs have made big changes this summer in terms of personnel, with each club hoping their new coaches can usher in new eras of style and success.
Chelsea got off to the perfect start with a 3-0 win at Huddersfield, while Arsenal's 2018-19 Premier League campaign spluttered into life with a 2-0 home defeat against champions Manchester City.
A London derby defeat will not necessarily be a disaster for either sides' season given Chelsea and Arsenal look likely to give their new coaches time to build for the future.
Chelsea XI: Kepa, Azpilicueta, Rudiger, Luiz, Alonso, Jorginho, Kante, Fabregas, Willian, Pedro, Hazard
Arsenal XI: Leno, Bellerin, Papastathopoulos, Mustafi, Lichtsteiner, Torreira, Xhaka, Mkhitaryan, Ramsey, Ozil, Aubameyang
Arsenal face a defensive selection dilemma with Unai Emery currently without a recognised left-back. Ainsley Maitland-Niles started in the role against Manchester City with Nacho Monreal and Sead Kolasinac both injured, but the youngster limped off in the first half.
His enforced withdrawal could see Stephan Lichtsteiner - who replaced Maitland-Niles versus City - start on the left flank.
Emery also has a tough call over his goalkeepers. Petr Cech was preferred to summer signing Bernd Leno against City, but struggled playing the ball out from the back - and he could be dropped versus his former club in favour of Leno.
However, Sarri will be desperate to win his first home Premier League game at Stamford Bridge, while Emery will not want to be beaten in the capital for the second game running.
Chelsea host Arsenal at Stamford Bridge with kick-off scheduled for 5:30pm BST on Saturday, 18 August
