Nobody has two elite players for every position. Even City don't. Look at how they've fallen off a cliff since Rodri was injured. If you're them you can't buy another Rodri and expect them to be happy waiting for their chance from the bench. Same with Haaland, thet had to let Alvarez go in the summer because he wasnt willing to play second fiddle. They've also missed his goals this season. You'll never manage a squad where you don't have a drop off due to injuries/fixture congestion.
Errr...they spent what, 60 million on Phillips who was meant to be their back-up Rodri? They then brought Kovecic in when Phillips wasn't working out. They most certainly did try to recruit a Rodri backup. It failed. That's on their recruitment/Pep (the Philips thing is bizarre to me).
Alvarez was an outlier in terms of what's being discussed. He was never a Haaland sub; he's a different type of striker who demands a different style of play. They obviously thought that with Foden, Grealish, and Silva, they had enough to play their 'false 9' if Haaland was out.
I will say it again.
Football is in the middle of a shift. There has NEVER been the demand there is on squads that exists today. Many of these players are currently three years+ into 11 month seasons of average three games a week with more travel than ever. It is untenable to expect trophies from squads of the current size.
We will start to see larger squads for sure, and careers will be shorter and more intense unless we u-turn from where football is going.
Finally, when I say elite players in depth, let me be more specific. In the key positions, I think you can afford no drop off IF you want to win now. For us, that'd be keeper, 6, and wingbacks. I'd add wide l/r frontmen (wingers) too. Right now, we have elite backup for Romero, arguably for 6 (though I feel we will in the long run have to do better there if we want to push for the title) and we have elite backup for a wide position. All other areas are development.
Again, I am all in in development and patience, but it is clear much of our fan base says they are but then go apebrick at results like Sunday's. I hope Ange gets the time.
