I mean I had an answer. It's literally written right there in that post you quoted. There's one successful manager that implements that kind of midfield and style of play. Trying to replicate Pep's midfield while not applying that same style very likely won't work.
Yeah, great, I agree. I'm not sure why you think I'm happy or why do you think I don't want us to buy a midfielder. I never said I think we currently had the balance right, that is your invention. I said I would prefer we wouldn't spend an extraordinary amount of money on a player that plays in the exact same position that our star player already occupies. Sure, Fernandes might be able to transition into a B2B midfielder but spending that amount money on a "might" is a bit risky. You seem to think that a normal CM isn't able to be creative which is just weird.
Really, it all just depends on the style of play the manager is trying to implement. David Silva and KDB, even Bernardo Silva and Eriksen were pure AMs when they came here. They were able to transition into hard working mids who are great in the final third.
We have enough inconsistency amongst the young talents in our team as it is with the likes of Rashford, Martial, Lingard, Lindelof, Scott etc. Priority wise, what our team first needs is players in the range 23-26 who are at the cusp of turning their potential into consistency. When the team has a stable set of performers, then we can focus on getting the best youth talents. Don't get me wrong, Felix, Sancho have world class potential and I would like nothing better than to get them. But, in our current condition, spending 100m plus on players who may or may not reach their peak won't improve our current team and situation. Bruno is at the right age to make the move and in the right setup could turn our average midfield sans Pogba into a top tier one.
Look at City and Liverpool template of transfers. Recently, their most successful signings have been players like Salah, Mane, Van Dijk, KDB, Sterling, Bernardo, Laporte, Ederson, Allison who were at the right time and age to make the jump from potential to consistent.
