The former national team manager was covering the Euro 2016 round of 16 clash for Sky Sports, and he was well and truly caught out when his effusive reporting of England’s performance was interrupted by Kolbeinn Sigþórsson firing past Joe Hart.
Saying that England were causing the Icelanders “all sorts of problems” and calling it “the perfect response”, McClaren even denigrates the opposition as having nothing about them but “the big boy up front” just as that very player scores what turned out to be the winning goal.
McClaren visibly wilts as the goal is scored, much to the amusement of the viewer who uploaded the video, who bursts out laughing and zooms in on the scoreline.
Wayne Rooney had given the Three Lions an early lead from the penalty spot after Raheem Sterling was brought down in the penalty area, only for Ragnar Sigurðsson to equalise within a minute.
Having also presided over a disastrous 2014 World Cup campaign in Brazil, when England finished bottom of their group, Roy Hodgson announced his resignation immediately after the game.
But arguably the star of the show last night was McClaren, who has previously made headlines for standing on the touchline with an umbrella and giving an interview in a Dutch accent.
