I’m with you on most of this, although I can’t write off any usefulness from Mount just yet. We know that he is a good footballer, and at 25 there is no reason other than terminal injuries that should mean he isn’t able to make any meaningful contribution for Manchester United. I don’t see him so much as a Bruno alternative either, but more a Mainoo alternative. Or at least both roles.
McTominay should have been sold at 20 and every summer not sold since then has been one too many so no arguments. Regarding Casemiro, I don’t know if him being a back up player is a genuine fiscal option. The opportunity to get his fee and salary off the books is more important than having him as an understudy.
Eriksen’s stock should be fairly high after an impressive Euros and I expect him to leave too. With any luck, I think he could attract PL interest still and we could get about 5m for him. I wouldn’t rule out interest from Brentford, which is basically Little Copenhagen, or potentially a promoted club looking for experience and quality. I think Leicester would be a good option.
I say all that to say, it may be worth keeping Hannibal rather than selling him for what is likely to be not much. Everton were interested in January and if they were to come back to the table we may be able to get 10m for him or so but no team abroad would pay more than half that I doubt.
