That is a possibility and it would facilitate our signing of players in January. I hope it happens, but it's not a given. The fact that we didn't offload them in the summer is a bad sign.
I still see us offloading a few players without necessarily signing a replacement. Wanyama is the one I see we could get rid of then and to a lesser extent Danny Rose.
Wanyama is one that I suspect Spurs have tried to sell for at least 2 years now - seemed odds on to go to Bruges in the summer with a £13m fee agreed between the clubs and a £65k pw wage almost agreed bur apparently Wanyama decided against it at the last minute. Problem is he has 2 years left on his contract.
And if he refuses to be sold he may well also refuse to be loaned. And if we simply do not register him in our squad (and I am not a legal expert) I do wonder if that might trigger a 'constructive dismissal' event ie we are depriving him of the opportunity to work. And that might cost us not only the 2 years wages left on his contract but damages as well - so might be £5m - £10m cost versus getting a fee in. If that's not the case I suspect a few other clubs would have also dealt with a few players that way.
The other overseas trained player I could see going is Aurier, who can be replaced (at least for this season ) by Foyth with Walker-Peters also there (albeit Poch clearly isn't a big fan atm). After those 2, the other overseas trained players who imo are the most likely to be candidates to be moved on are Dier, Sissoko and Lamela, but all three have their uses and I suspect the club would like to retain all 3 until the summer.
Spurs announced in preseason that Rose was given the opportunity to talk to other club(s) but nothing came of it. Biggest problem I suspect is to find another LB - unless that will be Sessegnon by summer.
So looking at the squad overall
Management - Our Squad 2019/20 - and the Rebuild ! there are 2 'HG' player spots available which could be filled in January. Problem is that there are not too many good candidates available.
To me the candidates might be :
Lewis Cook (DM) age 22 from Bournemouth - But he's just coming back from a year out with injury. Poch would also need to agree not to kill him in training until summer. But he's quality
Joe Gomez (RB/CB) aged 22 from Liverpool - He's unhappy as he has lost his place through injury last season and isn't being played. But would Liverpool sell to us ?
Aarons (RB) aged 19/20 from Norwich - Inexperienced. Not sure he's that much better than KWP. Would Poch play him
A few other options but probably less than 6 to 10 good enough for us. But these might not all be available !
