Chelsea survived a scare in the FA Cup on Saturday as they scraped past League One Plymouth in the fourth round and Kepa Arrizabalaga was the hero.
Plymouth took a shock lead early in the first-half but a clever flick from Cesar Azpilicueta ensured that the Blues went into the second half level.
But the match was forced to extra time, as Chelsea were left frustrated by the visitors' shot-stopper Michael Cooper, but in the first half of extra time Marcos Alonso edged Thomas Tuchel's side back in front.
