I don't think HG is a problem even if we sell Davies, Doherty, Alli, Winks.
The PL & EL squad max limit is 25, and if we breach HG rules by a few players we'll have a max of 22-23. But then there are unlimited U21s allowed in both competitions.
So we could have 22 players over 21yo, and then add Skipp, Sessegnon, Scarlett to make it 25.
Davies and Doherty are NOT HG for UEFA purposes.
Next season (without taking account of summer incomings or outgoings) are :
Club Trained - Kane, Winks, Tanganga, Whiteman (3rd GK) plus possibly Bale
Association trained - Hart plus possibly Dele.
u21 players - Skipp, Sessegnon (Scarlett and Devine will make appearances but probably not be starters - just too young).
So we need to ensure we have not more than 17 QUALITY overseas trained players to start with.
And with
Lloris and
Aurier having one year left on their contract plus players who we need to move on
Sissoko (age, not very good),
Aurier (one match away from a conceding more goals),
Lamela (injured for 2 matches out of 3 so cannot be relied upon),
Doherty (just hasn't found same form he had at Wolves), - so
five who might need to move on (
Lloris will stay if he signs a new contract so it might only be
four ), and what happens with
Vinicius (buy or loan or replace to have a back up striker ).
So that's a minimum of 5 players to sort out, before considering those we might want to upgrade on - whether overseas trained or not. And players who may wish to leave (rumoured Dele and Winks).
And that still leaves the likes of Dier and Davies who some posters want to be on the out list
But even if we can sort out 17 decent overseas trained players (a major job by itself) if we sell Dele and Winks we have Kane, Tanganga, Hart, Skipp and Sessegnon to make a 22 man squad.
IMO that is just too tight, so any opportunity to buy a QUALITY HG player or two to the squad makes absolute sense - and we need to lose an overseas trained player anyway to get Rodon into a UEFA squad..
