Absolutely not wrong at all to want that, no. And I fully expect it to happen. I'm jusy saying that, if it doesn't, it can still be fun as we are in such a good position as a club.
As for the squad growing old, I think that's partly down to their success & a reluctance to change, prices & ffp & the fact neither manager gave a fuck about promoting kids.
If none of our kids are as good as Kolarov, for example. I bet we could have found a kid somewhere who is & use him& Clichy plus a academy kid to cover that spot. But it's easier just to pick Kolarov. Same as it's easier to pick half fit Sterling or Yaya than change the formation & fit a kid in now.
All the 'squad' players should be kids imo except maybe one or two.
