I suspect that Caicedo is out of the price range of Liverpool (see Bellingham pull out), Spuds and Arsenal. Chelsea will have FFP barriers so I can’t see them splashing the cash. It’s then the Manchester clubs, Newcastle or abroad to somewhere like PSG.It will be tough to hang on to everybody. Even tougher if we don't make the CL (thank you Attwell and VAR). We've already turned down something like £70M for Caicedo (and I suspect all his starving siblings back in Ecuador aren't getting any less hungry! ) so fully exxpect bids to be made for several of our players.
I think, though, that losing one (for an eye-watering fee) may actually be part of the sustainability and development plan. If that happens, I hope they go to a proper club, not to some over-rated over-hyped dross like Spurs or Chelsea.
Manure would be the one I’d worry about as he is an upgrade on all their midfielders. Stick him next to Casemiro and Manure challenge for everything next year. Hopefully, their ongoing sale saga severely restricts their transfer business this summer.
