Tough to disagree with you mate. Good points. But I'm thinking Germany at the last World Cup. It was a team full of efficient, stars rather than one with stand out dangermen in the mould of Messi, Ronaldo, Neymar or Hazard. Ozil does not fall into that category for me. Don't get me wrong, Germany had great players but they didn't have that type of X-factor, defence splitting, dangerman in their squad. Going back in history, Germany has mostly been like that.
Leicester City was also like that two reasons ago. I am not saying we do not need those types of players you describe (I absolutely love them in teams). Just saying that you can build a winning team despite not having such. Admittedly, it's a bit harder doing so.
Having said that, I think Martial, Pogba, Miki, Rashford and to an extent, Pereira, have the potential to become X-factor types (of course not at the Messi, Ronaldo levels).
