I think it's more about Betis needs to sell Alex to balance the books, they've already tried to push him to sign with Nottingham Forest in summer but he rejected them.
Surely CL qualification would grant that?
And imagine that they won LaCopa and will play in the Saudi Cup on Thursday yet still won't earn enough to balance the books. Betis have a net balance of 37.7m surplus over the past 3 seasons too.
LaLiga clubs are seriously limited in their growth, and thus investment, potential. Tebas always cites the FFP as a means to avoid what happened with the likes of Depor and Zara but ignores this was pre more equitable TV rights distributions, pre-international rights sales increases, pre-national rights sales increases and pre-CVC.
Meanwhile thanks purely to sale of future rights % Barcelona spent more than PSG this Summer, yet the total transfer expenditure of the whole of Ligue1 exceeded the transfer expenditure of LaLiga last summer.
Over the past in-fact 2 years Ligue1 clubs have spent 150m more in transfer fees than LaLiga clubs, and that is with Barcelona and Madrid outspending PSG by roughly 100m over this period. So it is not a case of Ligue1 spending power being skewed by PSG, but that they have more relaxed FFP that's incentivising investment for the other clubs.
