Di Maria, Falcao, Ibrahimovic, Pogba, Ronaldo, Sancho, Varane, Casemiro? If that aren't big names, then I don't know how you define that term?!
You made my point. You named 8 players that have been signed across 8 years. I kind of knew that it was where you were going to go and that's the fallacy, those players where signed alongside a plethora of players that weren't big names and especially around young players. Did the club sign big name players when the opportunity arised? Yes, but the strategy has never been to build a squad of big names and we never had a squad full of big names.
And by inflexible, I meant inflexible, the character trait. Which can show itself in different situations.
