Lol said the same the other day while watching reactions to Barca vs Madrid.
So many fans from Africa, middle east and Asia in our Jersey's celebrating.
Every single one fake lol.
If those bastards bought Jersey's we would fix barto's mess in 1 season.
A fair amount were also watching on laptop's, so we know that's also free.
To be fair I am speaking more of South East Asia than Japan/Korea (though I suspect China would be more similar to SEA than Japan/Korea in terms of fakes).
So the major incomes for the EPL clubs would be global tv rights, and friendly tours which would be paid for by companies and governments rather than actual ticket sales.
So any global fanbase figures (and this would include Barcelona) in emerging markets and SA would be greatly exagerrated in terms of dollar impact that it actually brings, and would be more as a metric for regional sponsorship deals negotiations than actual shirt sales. Especially when they have exposure to the factories that produce the original jerseys, creating an oversupply of the "fakes" at a much lower price.
One of my suggestions would be domestic exclusive official fan jerseys at a lower/mid price point. So for example Singapore has their own domestic Barcelona jersey, Malaysia has another and Indonesia has another. Sure these may have knockoffs created if the production time is long, but on the other hand you may increase income by having fans in this region wanting their domestic editions, plus collectors wanting all of them.
They could be authenticated by NFT with localised perks for example.
I don't know why I am giving them this world class advice for free
