Yup, Braithwaithe sadly will have to be sold - not this season btw, he was never going this.
In order to maximise on a sake ehstbwe need to ensure us each season we have at least two very sellable and in demand assets, that way it allows us to dictate conditions or which one we sell depending on fair offers - you saw this happen with the sale of Onana.
Next season trust me if all we have to sell is Braithwaithe we will get low balled again, united new exactly what they were doing btw, we just got around it thanks to a bit of fortune, Luiz going to Bayern created a demand from villa that was unexpected (arsenal and the likes were basically hovering and delaying in order to get him a lot cheaper imo).
Until as you say revenue alters in the new gaff, we will still have to sell each season to stay out of issues though.
Even say a Braithwaithe sale for 100m won't alter that next season, because the season after we will still have the amortisation costs ticking (it's also why it's suicidal if we invest each season what we bring in like zat wants).
