Boris Johnson was left red-faced when he was forced to concede he had no idea who was playing in this Sunday's Capital One Cup final.
The Mayor of London was quizzed on who he would be cheering on when Chelsea take on Tottenham Hotspur at Wembley this weekend.
And the 50-year-old admitted that he no clue about the game, despite two giants of London football squaring off for the first piece of silverware of the campaign.
When asked about the game on
When informed about the meeting between the Jose Mourinho's Premier League leaders and Mauricio Pochettino's Spurs, he added: "Right, well, obviously London is going to come out well from that particular encounter."
The incident isn't the first time that the Mayor has been caught out for his lack of knowledge for football however.
In 2006, Johnson drew widespread hilarity from fans across the country when he launched into a rugby-style 'tackle' in a televised charity match against a German opponent.
Clearly eager to close down his man, Johnson enthusiastically galloped over to the winger before stumbling into a challenge that was akin to a WWE-style spear.
Mourinho, who is without the suspended Nemanja Matic for the game, claimed that the match was the most important of his career.
“This cup final is the most important cup final of my career,” said Mourinho. “More important than the Champions League. More important than the other cups I’ve played before.
“Do I look stupid? It’s because it’s the next one. The next one. I just think about this game. We have a final to win on Sunday and nothing else matters.”
