Yeah ok I see your point. I do wonder where the trope comes from then, I don’t think it’s just the Ronaldo transfer.
Perhaps losing out to Barca and Madrid for top tier players over the years adds to the notion aswell?
Ones I can think of off the top of my head are Modrić, Bale, Benzema, Varane, Ozil all opting for Madrid over the years instead of us (or so the rumours go). More recent examples of it being a no brainier for wonder kids like Touchemeni and Camavinga choosing to go there instead of here.
It does feel as a United fan if that there was ever a choice between us and Madrid over the years, we would lose out.
I also seem to remember Darren Fletcher on Monday night football saying Fergie was good at sweetening up the European players at United as there was always the potential for them to have their heads turned by Madrid/Barca etc. But didn’t have to mollycoddle top tier British players like himself, Rooney, Ferdinand etc as he knew the British players would have dreamed to play for United and see that as the pinnacle of club football, instead of looking to move abroad.
But I do concede your point that players don’t ‘always leave us for Madrid’ like first suggested. And I’m not now changing the goal posts, just adding to the discussion as to where this feeling amongst United fans could arise from.
