Tosin could certainly have been handled a bit better while he was at City. Centrebacks seems to be an area we are very cautious about and stick with tried and tested rather than bringing through youngsters at all. I think he could probably have been given Eric Garcia's chances though.
However, we've just won 3 title on the trot and done the treble. What we are doing is working!
If we want to persist with a 3 or 4 centrebacks system, there's an argument that maybe the 5th or 6th centre-back should be from the academy and get some game time to help them develop I to a first choice level. There are undoubtedly some games during the season where we wouldn't lose out by Harwood-Bellis or Callum Doyle playing the last half hour. But long term these players want to be first choices somewhere and doing it here is difficult.
For me, Tosin now is an ok centre-back. He's tall and decent technically, so there are positives, but he's not good enough for our level. He isn't mobile enough to play in the wide areas the way we do, so he'd have to play as the central DC, but can anyone honestly suggest playing him ahead of Ruben? Don't be daft. And even if he wasn't available, any of our other current defenders would play ahead of Tosin. Stones is on a different planet in terms of footballing ability and even Laporte could barely get a game.
(Shakes head and walks off muttering)...
Edit - tbf, I think he's capable and if Maguire can play for England, so can Tosin. I had half expected him to have at least one cap by now, but it hasn't happened. Doesn't mean it won't. But these days an England cap doesn't mean you're good enough for City either, most aren't.
