Tottenham Hotspur's loss to Brighton & Hove Albion on Saturday felt like a bolt from the blue.
Not only did they go down to a last-gasp goal on home soil, but the ruthless efficiency with which Antonio Conte's team had been playing in the previous weeks didn't point to a significant slip up.
It means that Spurs have been dragged back into a major scrap for a top-four finish and supporters will be watching on anxiously this week. Rivals Arsenal and Manchester United at least have challenging fixtures away at Chelsea and Liverpool respectively.
