I often see people use 'have' while refering to football clubs, or any other sports team. Say, for example: in today's edition of The Times of India, in an article about Manchester City's victory over Liverpool, I read the following sentence: "Manchester City, who have been imperious at home this season, fell behind to an early goal by Liverpool's Philippe Coutinho." Now, Manchester City is a club. And since it is a club, my question is: "why is 'have' being used here?". Thank you.
