For just a year though? He’s untouchable in the France team so he’s not got anything to lose by going there for a season. Fill his boots with goals then come back to a Europe and Real Madrid. If he was signing a 5y deal maybe, but a 1y deal won’t have as huge effect as I’d it were more permanent.
Of course it’ll get more eyes on their games but for the overall growth of the league long term I’m not sure.
