Thats 5 players, 2 of which have never kicked a ball in the senior side and I dont even think the other 3 have 1000 minutes between them.
I am all for academy players, I loved it watching Foden, Doyle, Bellis making debuts as local lads who are all City fans, but they've got to earn their place and as a club who need to be competitive and one of if not the favourites in 4 competitions every year, young inexperienced players have their place, but who do you leave out?
Jayden? Thats one of Sterling, Mahrez, Bernardo and currently Sane you're leaving out instead
Rogers? Kun or Jesus
Bernabe? Sane, Sterling, Dave, KDB, Gundo, Bernardo or Foden.
Tommy? Rodri, Gundo or Kev
THB? Laporte, Stones, Otamendi, Dinho, Garcia.
We've got two lads who need more games next season. Phil and Eric, and they're slowly breaking through showing how hard it is. Phil spent a year with the first team in 17/18 barely ever playing. 18/19 he got a tiny bit more and started showing his true skills, and this year its a bit more. Its 1/2 season process without loans and thats assuming Phil gets his step up next season.
Before you put words in my mouth Ezzy like you do with anyone who disagrees with you this is what I believe: When there is a gap in the squad needing replaced, the club should always look first to the academy to see if there is anyone likely good enough to fill that spot effectively. Thats what happened with Phil and sort of with Eric. So lets try this with the current squad.
CB is a problem position, with us expecting to sell Otamendi and/or Stones we need at least one new CB.
So looking at the academy you can say the two likely candidates are Eric (now established first teamer and hasn't gone back to the academy this season) and Taylor (has made his debut & Pep is impressed but not full time with the first team). I think if both were to be here next season as full time first team it would effectively halve the minutes available to them, as Laporte and Fernandinho are still here & one of Stones/Ota might be or a new replacement, so naturally you'd assume to sending one of the two academy lads out on loan to get regular game time, which I'd guess would be Taylor - less minutes than Eric and a bit younger too, then re-assess upon his return from loan whether bringing him into the first team is better for the squad either by not buying a new player or selling a current one who's ready to move allowing Taylor to fill that spot.
That is my belief. If the squad is considering a transfer in, look to the academy first, if the manager doesn't feel theres anybody ready for this season and risking waiting a year for a youngster is too much, buy someone. If theres a player in the academy worth waiting a year of development for (like you could argue Phil was in 17/18), promote him to give occasional minutes and continue development in the EDS or loan out to a suitable club ready for the following season.
Out of the 5 you originally listed for the coming 20/21 season, I think Braaf could step up in place of Sane. Morgan definitely isnt ready and I wouldn't be risking it. One of Bernabe or Doyle might be useful as a bit part first team squad option but not both (like what I described above for CB) and Taylor as above probably is best suited to a loan spell if theres a suitable club - Blackburn have done a fabulous job with Tosin, so maybe he returns as the replacement in at CB and Taylor goes there for a year of development.
