Things I know...
...Lozano is good. Not because he had a great game today, but because he's been outstanding for PSV, Mexico, and Pachuca before that.
Chucky is also versatile. He can play as a true wing and as a central attacker.
Mexico's front 3 includes a right back, Layun, and Carlos Vela, who is absoutely still good. He was no slouch at Real Sociedad, even if he never really made it at Arsenal. Lookman absolutely doesn't get into that side ahead of Chucky or Vela.
Lookman is going to be a contributor next year, but to ask him to start a left inside forward, is not the best idea UNLESS we are buying a stud left back, a stud box-to-box player, and an elite center back.
Sigurdsson is not an 8, should never play 8, and the idea that we should take our most creative midfielder and make him play a position he's never EVER played before is just absurd. We paid money for him to score and set up goals. Like he's done at EVERY team he's ever been with. He should be the pivot in Silva's middle 3. It's the perfect position for him.
