A problem I sense is that we have a bit of a gap between the first-team players and those youngsters that could be entrusted with appearances in the League Cup. In the first two rounds, only Muric, Foden, and Diaz started, which meant we were already over-reliant on various first-team squad members; never that keen on the idea of first-team regulars needing such games to gain fitness/focus. Often think that we would be better served having 3-4 of our loan players back playing in these games and then supplementing the first-team, ala Zinchenko, more regularly.
It's also hard to use the 'treating tournament with respect' line and then field a squad of youngsters, but maybe if we can go on and win the treble, it might give us the opportunity to say we've done it, we've enjoyed the challenge, and now we've learned from our experience and are instead going to prioritize.
