One man's opinion, but an interesting list. as I said before, I expect Spurs to have a "net spending" budget of £100mm or more this window. they can do a lot.
In: Ndombele (65mm - seems likely), Maddison (60mm - I rate this as unlikely, but worthy), Wan-Bissaka (55mm - another unlikely, but not impossible), Sessegnon (20mm - this one's been around for so long, and now the player won't extend his contract at Fulham, so seems likely), Ziyech (25mm - rumored to Arsenal, or Bundesliga, so I doubt this - I'd rather see van der Beek, for an extra 8-10mm), Ward-Prowse (30mm - really doubt this one)
Missing from this list is Clarke from Leeds, long rumored ~20mm
Out: Aurier (25mm - about what Spurs paid for him, not unreasonable), Trippier (25mm - especially if to Juve or other Serie A, valuation seems appropriate), Wanyama (20mm - if Spurs land Ndombele, then Wanyama is certainly surplus), Eriksen (I actually think he will resign with Spurs - Real Madrid has blown their budget), Nkoudou (7mm - bye bye), Janssen (10mm - bye bye), Onomah (5mm - bye bye)
The listed ins/outs total £93mm net spend. Poch can really do a lot with a theoretical £100mm budget.
