You do realise there are 54 players currently aged 15 and over in the academy, do you seriously expect all of them to join the first eleven.
Spurs have developed one player in six years? There are currently 31 ex Spurs academy players who have come through since 2010 playing professional football - you clearly don't follow our youth players very closely.
as for making it as Spurs - Rose, (never started for Leeds) Kane, Winks, CCV, Georgiou, Sterling, Skipp, Marsh, Eyoma, Tanganga, Parrot, Whiteman, Austin, Cirkin, White all still on our books .... pretty sure more than one of those have played for us ......
It wuld not be unreasonable to expect say 2 new academy players a year to start to play in Spurs first team (including pre-season) and at least one to join first team squad to play first team football on a more regular basis. Reason being that each year Spurs have 2 - 4 really good youngsters in each year group.
And over a 6 year period I would have expected to find maybe 4 or 5 players to have joined the first team - in stead of buying jorneymen footballers for Spurs first team squad.
Rose had started to play at Spurs pre-Poch, CCV has never played a PL match nor has Georgiou, Marsh, Eyoma - Sterling played a couple of minutes, - Whiteman and Austin have not played for Spurs first team. Some of them because they are not good enough, others have been good enough (as judged by England youth coaches etc)
The whole issue of the Poch era is (and I repeat) only ONE player, Winks, had significant time and is currently part of the first team squad.
There are probably a dozen or more who had a few minutes in one or two games - and that was it. Clearly Poch never had any intention of bringing the players through.
Skipp played as Spurs were short of players - but last season hardly got a look in under Poch nor did he get a chance to go on loan to play the minutes every 19 year needs - same with Parrott.
Despite his reputation, Mourhino has probably done more for Spurs academy players in the year at Spurs than Poch did in his 6 years,
The issue which you fail to comprehend is Poch allowed youngsters to train with the first team squad and where he decided they were not ready for first team minutes, did NOT allow them the opportunity to go on loan to get the experience he clearly thought the need to play at Spurs.
And that has the consequence that now Spurs enter the current season with 2 Club trained players in their squad - Kane and Winks plus the bought back Bale, with Rose likely to leave - meaning Spurs cannot get to have a 25 man squad for UEFA, unless one of the 21 year old inexperienced GK's (no loans under Poch) is 3rd GK. Also puts pressure on Spurs to buy HG players from other clubs to get our squad numbers up (Dele, Doherty, Hart, Sessegnon currently)
Had Spurs been seen to be bringing the academy players through better we would have a better squad (saving money on squad players to buy on better layers) - and not had the ridiculous situation where Fulham fans think that Onomah (given away last summer after being played as a RM by Poch for token minutes in many matches and never as CM where he plaed in Spurs youth and Fulham) is largely responsible for getting them back in PL or players like Spurs u16 captain Mandueke refusing Spurs Academy scholarship offer as he thinks there is no route to the Spurs first team (and now a first team player at PSV scoring goals and making assists having taken Bergwijn's place - at age 18) or Binks leaving to go to Montreal and now Italy for the same reason.
I thank Poch for the coaching he did for the first team and getting us to CL final (and Cl in 4 successive seasons) but not for his utterly incompetent handling of most of the academy players during his tenure or his over training/playing many first team players which may well have caused many of them to burn out too early.
