If Paratici is recommending to sell one of the best attacking players in the league (and arguably the world), who's absolutely integral to the way we play, well, I think he needs his head examined. That's assuming (1) that Conte stays, and (2) that Kane is happy here (which may depend on #1).
I think we're still feeding on the scraps -- even with CL football, we cannot compete with ManU, Liverpool, Emirates Marketing Project, PSG, etc. in terms of transfer fees or wages. Kulu and Bentancur are both clever second-tier buys that have worked out. Not all will, but that's the space we're working in. CL qualification would help us to stay "best of the rest", of course.
As others in the thread have said, we need to get whatever we can from the players currently outside our first 14. £25M for GLC may well be possible, while £10M for Ndombele plus hefty sell-on clauses, £15M for Winks, and £10M for Rodon don't seem ridiculous. Add £40M and that's enough to cover Kulu and Bentancur plus two decent players. Hopefully. Add in a "friendly free" from Bale / Dybala / Eriksen, and that's looking like a good window.
