Chelsea boss Mauricio Pochettino suffered his first defeat as Michail Antonio's superb strike and Enzo Fernandez's penalty miss condemned the Blues to a 3-1 loss against West Ham on Sunday. After last weekend's 1-1 draw against Liverpool, Pochettino's side wasted a lively performance as they paid the price for sloppy defending and wasteful finishing at the London Stadium. Antonio blasted West Ham's decisive second goal after half-time and Lucas Paqueta added a late penalty to leave Pochettino still waiting for his first Premier League win since taking charge in the close-season.
