We'll only really know when things play out after the summer but I'm sure it's about the player trusting Poch, his way. I think he would have liked initially Bentalebs attitude, he's a feisty character and tough competitor but sounds as though he took this too far, pushed or maybe even demanded too much from Poch. It's hard to get the balance right. I just think both KWP and Winks have given themselves to Poch, if he says jump they say how high.
The Spurs factor I think is the 2% (or whatever it is, that tiny X-factor) that makes you get to a ball a 10th of a second before the oppo, that enables you to press in the last 10mins of a game when all you want to do is sit down. Probably this doesn't come out in training???
The problem I have with your statement is that Poch's original idea 4 years ago was that everyone would come through his coaching, and no loans,
And if that works, I'm all for it.
Roll forward 4 years and only Winks has come through under Poch (possibly Skipp too but we'll only know when he's a year or two older, and KWP 4 years after his debut has only played a dozen times, so still all to be proved)
Now I think Poch is a bit of a pragmatist and, seeing the limited throughput and what other PL clubs achieve, he said a year or so ago words to the effect that loans weren't all bad.
Whatever way he moves I thin k he has to move away from his original statement - and one way to refine it would be to make better use of pre-season to bring youngsters through. He did more in pore-season 2018 than ever before (maybe due to WC taking away a lot of players) but Spurs still won the pre-season tournament, which I think might have got him thinking 'the kids are alright'. So I'm looking forward to see what happens in pre-season 2019, who goes to it and who plays next season (and with Copa America overlapping taking away CB's Sanchez and Foyth, AM's Lamela and Moura) he has to ise some youth.,
Reason he has to change and bring through some youth is the squad :
Club trained - Kane, Winks, Rose, one vacancy
Other FA Affiliated clubs trained - Dele, Trippier, 2 vacancies
So added to the 17 overseas trained players in the squad (currently 19
for UEFA purposes) that gives us 22 players (including 3 GK's) in the squad, which is only just ok,
And I understand that excludes Skipp and KWP, but either way he either has to bring through more club trained players (as discussed above) or buy them back (probably only Bentaleb and Veljkovic fit that category) or buy home grown players trained by other clubs......high price and not too much choice.....and arguably no better than coming through the Spurs academy if they had experience.......
So Poch's decision how he fills that gap, but its a must to get to a squad size where a few injuries do not undermine the season.
