Really? The kid has played 1 full game in the Capital One Cup and 60 minutes of a dead Champions League rubber against Championship quality opposition in the form of Celtic, and you think that constitutes evidence that he's good enough for a regular or semi-regular first team berth? I'm not knocking Maffeo, but if we're going to decide someone is good enough (and he unquestionably played well at the Swamp in an out and out defensive role, but looked distinctly ordinary and one paced in a more advanced position against Celtic) on the basis of 1 full game at senior level then Michael Frontzek would be the best left back we've ever had. Whatever, the boy is 19 and if a loan to Girona helps him develop further then that's good news for us as far as I'm concerned.
As a separate issue, people have hugely unrealistic expectations of City's Youth Academy IMO. Yes, it's better than what's in place at most other clubs, but the reality is that we are an elite level outfit, unquestionably one of the 10 best in world football, and for youngsters to make the leap into our 1st XI (as opposed to say Southampton or Everton's) they will have to be not just good but absolutely exceptional. By getting our youth teams to all play the same way the hope is probably that we can bring in a number of players to fill particular roles in extremis - squad players if you like, capable of fitting in as seamlessly as possible when injuries to those above them dictate - and make a bob or two from flogging others off. Unearthing a superstar will be a very very rare occurence, and of the current crop of 19 year olds, I'd say only Alex Garcia has truly convinced me he has the strength, ability and temperament to do a regular first team covering job at this moment in time. Some of the U17's - ie. Diaz, Foden and Sancho - offer greater promise IMO, but either way just because someone looks half way useful in their Capital One Cup debut it does not automatically mean they are ready for the 1st team. I suspect Pep knows what he's doing
