Frankly Rado this marketability argument is one of the worst I've heard. You can tell me to deal with it and act like Pogba is akin to an F1 pay driver all you want, but I suspect if you offered this opinion to fans of any other club you'd be laughed at. I think it would be particularly amusing to Chelsea fans watching their team romp home to the title with a player signed for a third of what we paid for Pogba at the heart of their midfield that they were somehow missing out on some marketing masterstroke that they didn't splurge a world record fee on a midfielder who (with the best will in the world) isn't currently worth it. I'd rather we sign football players because they're good at football than because of their brand appeal.
Pogba is a football player bought to play football; the very fact we have to resort to some vague intangible accountancy to try and justify what we paid for what we got is itself an admittance that what he's doing where it counts isn't currently good enough?
And how much does it mitigate his performances? Knock £10m off the price? £20m, £30m? £40m? How marketable does he have to be to justify giving us comparatively less than, say, Alexis gives Arsenal?
Of course ultimately the numbers are currently irrelevant. We've bought a player who had a reputation as world class and paid what we thought he was worth for one reason: to improve our team here and now and in the future, and The issue is that he is failing to live up to that reputation, and he's struggling to make the expected improvements on the pitch. If you're not worried about him then bully for you, but the amount of goalposts you're having to shift to not worry about him does hint at the fact that maybe you expected more to start with too.
