They, and the equally deluded Liverpool fans, have this bizarre view that our revenue can't be bigger than theirs, because they have "more fans".
Even if we assume they have more fans (and evidence from social media numbers tends to dispute that) they can't get it into their pea-sized brains that there is no correlation between the number of fans and revenue. Possibly there's a view that a large fan base might be attractive to sponsors but I'd love to see some quantitative evidence of that.
United have DXC on their sleeve, who are an IT Service Provider formed by a merger between CSC and HP. I can pretty well guarantee that united fans haven't been rushing to sign contracts with DXC, or buy Team Vkeeper for their laptops. And I'm equally sure that Standard Chartered don't rely on Liverpool fans' accounts to keep their business going.
For these sponsors it's about exposure. The PL and CL are two of the most watched sporting competitions on the planet. Getting that exposure at a CL Final is like buying a Superbowl ad. This season was be our 12th consecutive season in the CL and our 13th consecutive season of finishing in the top 4 in the PL. We've won the PL 7 times to date and have now won the CL.
Etihad, and our other key sponsors, must be delighted. Because that's why they pay for the exposure.
