City treating Savio that way is fine imo. They've had better players, they have and should have higher standards than ourselves. They have no need to wait 5 years for Savio to become a decent player when they are trying to win titles right now and have both the pull and finances to attract pretty much any player on the open market.
Maybe with your general comment you are correct and as a club we don't have the stomach but at the same time we've rarely actually purchased the players who it has been worth putting that time into. Even when those players have moved to other clubs we see they usually aren't top 6 level players. Probably what causes the friction with these players that need development is the over hyped expectations. We always hear such and such is generational, a future England captain or one of the top prospects in Europe. When you attach those expectations to players the reality is often going to be dissapointing.
For me at least, its not a lack of patience (in the case of Tel). I don't mind giving him time to develop, I just don't believe hes ever going to blossom into someone we need. So its not a time thing, its fundemntally I just don't believe he has the raw minerals to be a player that when his development is complete that we would want to sign. An alternative example is Papa Mata Sarr, i've always thought he has massive potential, I would give him all the time possible even now to develop into the player we need because i believe he has it within him to become such a player. I'm begining to feel similarly about Moore, I already feel that way with Odobert. These are players I think its worth investing our time and respources into simply because I believe in their potential whereas I don't with Tel. Hopefully i've misjudged him and he proves me wrong.
