Really interesting question OP.
This is very much dependent on buyer and seller obviously. Looking at seller, THFC have a (deserved) reputation for getting top dollar which I reckon means we don't always move players on at the right time. The massive fees for Modric, Bale, Berbatov were when we really didn't want to sell our crown jewels but got bit the bigger fish. The only player on that sort of category right now is Lloris, maybe Eriksen by the end of the season. Of the ones the OP mentioned you could argue Kane fits into that category. However, he is still far from proven and what happens when the form dips? Hes not got the experience of Lukaku, similar to Jordan Rhodes but I am sure that would be an undervaluation. Maybe a similar value to Sturridge two years ago when he went from Chelsea or Welbeck to Arsenal ? Around £20m I guess???
Mason, Bentaleb haven't shown themselves to be anything that will capture the imagination in the Premier League yet. Decent midfielders, but in that Huddlestone/Livermore field, £5-£10m
Offer Levy over £10m for Rose and that's a done deal, especially with Davies coming on and the now surplus of full backs.
Townsend, we could get a big wodge for. He will never be as good as Bale or Giggs but he is underused at Spurs. Stick him any other PL team for a season and he will get you 10 spectacular goals a season plus more than that in assists (intentional or not).
We could get even £15m for him
Shut up you idiot Kane £40m at absolute least the boy is a BEAST
