Its part of a bigger issue which requires sorting.
When Poch first arrived he said he didn't like loans as the youngsters might pick up habits he didn't like (possibly true and perfectly reasonable from Poch) and that he would develop them at Spurs.
Problem is that whilst players who have had game time elsewhere are developed by Poch, only Winks has been developed (in 4 years) to playing regularly in the first team without having game time elsewhere - but we hope Skipp will double that total.
So as the club needs to have a minimum 4 Club trained players to get to a squad of 21, and an additional requirement to have up to 8 players trained by FA affiliated clubs (including the 4 specifically club trained) we are constantly a little light on numbers atm. So its in the club's interest to develop them - its just under Poch we seem to have largely lost that ability (whilst ManU, Liverpool, et al are doing better than Spurs)
Poch is evolving as a manager, he's realising that there's the perfect model in theory and then there's reality.
Take Edwards for example, in theory Poch can sit him down, teach him how to be and Edwards will take it on board and be a flier with us. The reality is some people need tough love or a wake up call and nothing is better for that than experience.
In theory Poch wants an institution at Spurs, he wants a hierarchy or power, a school of excellence and his way, his style engrained in them. The reality is the human level of the game, the greed,the ego, the lack of fear, maturity, different personalities and attitudes make that long term theory hard to achieve.
Edwards wouldn't listen so what do we do? Cut our ties with him or cut out his opportunity for brashness or a lack of desire to learn by throwing him the harsh reality that unless he does learn he'll end up at a level where he turns out for relegation fodder in the Dutch League year in, year out. It's got him away from his so called ego, lack of wanting to learn, his rumoured bad crowds, all the things Poch probably highlighted as problem areas for him as he tried to develop the player and the man at Hotspur way.
Experience changes thought processes. What Poch said when he first joined the club doesn't necessarily mean that his philosophy is still the same. I don't think KWP needs an attitude or a reality check but I do think he needs a run of games to develop his reputation for what he's capable of. He won't get that at Spurs it seems so trust that the kid is going to be OK, find a football club with a similar philosophy to how you want his development to continue and trust in process of it all. Pochettino is still a young manager, he's only managed a top club for 5 years now, he'll constantly change as he learns from the game
