Chelsea have now suffered back-to-back defeats in the Premier League after losing 1-0 to Arsenal at Stamford Bridge.
The Gunners have now won on their last three trips to west London, with Gabriel Magalhaes poking him the winner from a Bukayo Saka corner. The Blues struggled to gain control of the game with Pierre-Emerick Aubameyang failing to make an impact as he faced Arsenal for the first time since leaving the Emirates Stadium in January.
Chelsea went into the clash with a number of injury issues after Kepa Arrizabalaga, Reece James, Wesley Fofana, Ben Chilwell, N'Golo Kante and Carney Chukwuemeka were all ruled out. The defeat was a painful one for Chelsea supporters, with Arsenal fans enjoying the bragging rights for another season, with Potter now needing to find a quick fix ahead of the World Cup with a Carabao Cup tie against Manchester City up next for the Blues.
