Shows the intent to build a new team for the long-term...
Agreed and that's good to see.
We do have immediate concerns with the squad, but we simply can't compete with teams that have a lot more money than us if the plan is to continously fix short term concerns quickly (usually takes quite a bit of money that).
Indeed and its long overdue.
To some extent we've tried. Sessegnon, Clarke, Lo Celso, Ndombele, Bergwijn, Hojbjerg, Rodon. Even before that with Janssen, Sanchez, Aurier, Foyth etc. All falling into that 25 or younger, some in their late teens group of signings.
Quite a few of them could very well still come good. I may have forgotten some, but the only real success in that list so far is Hojbjerg (I get that it's still fairly early for some of the others).
We just haven't succeeded as we once did at these signings imo, but we have tried. Even under Mourinho there were several signings with more potential than immediate quality.
We must get back to getting more of these right though, and continue that process.
