I don't think many people are arguing for throwing our EDS kids straight into the first team, I don't see how a 17/18 year old has a chance of being a squad player at one of the top teams in the world.I get that many, many posters think City need to throw a few players in at the deep end, but this is not your Granddad's Man City anymore. Rather, this is a team that literally needs to win silverware next year, and I'm not just talking about the League Cup! To do that, Mansour has opened the cheque book yet again to buy a versatile intl for every position and a spare for almost every other position. Even at the full back positions, we are looking for 4 current intls, because the Premier League, League Cup, FA Cup and the CL means two games per week every week, and even more over the key holiday period, so almost every position needs seamless rotation, rest and recuperation time. Personally, I'm not sure Tosin is ready to be a seamless squad member in a back two containing Kompany, Otamendi, Stones and Kolarov, even before we possibly buy a high priced A.N. Other. That said, if a decent bid came in for Ota or Kola, then he may have a chance to get some game time.
He is cultured, but young, and while I agree with the nugget "if you are good enough, you are old enough," but in City's "flying full backs" system, the center half position is a vital position and requires the ability to cover two positions at times. One year of quality football at a decent club in a decent league against canny (full grown men!) forwards will be significantly more helpful than training with the First Team Squad but only really playing with the EDS and u21s.
Instead, we (or atleast I) are advocating for giving the players who do well on loan the chance. As Neville above me mentions, Denayer was ripe for the picking, he should have been a squad player after playing men's football for Celtic, but we messed that up. Now, I don't think the loan to Turkey was necessarily bad (as he mentions) because he actually played well there, but the loan to Sunderland fucked him up and there is that thing with continually loaning a player isn't a huge confident booster.
One issue with the Sunderland loan for example, was that he was at an awful team, one could make the argument that as a defender that this is perfect because he will have to defend so much, but this wouldn't be the case at City, where he would have to defend and play a different way because he wouldn't be on the back foot for 90 mins. This is why the Celtic loan was great, he played for the best team and learned to play as a leader. This is why Roberts loans was so great, at Celtic he spent the vast majority of the time learning to attack (which is what City would be doing). Now Roberts is 20, and I'd argue ready for a squad role, this would also show youth can have a clear progression to the first team, EDS->(impress alot on loan)->squad player
