Everything I said in those posts is correct.
Ronaldo has been bang average this season, and would have been worse if he wasn't playing in a one-team league, which Juventus will win without even trying. That's why he moved there. That's why he didn't move to Man United, despite professing numerous times that he loves them. Because that would have been a genuine challenge.
When Juventus inevitably win Serie A for the 8th season in a row, you will say that winning Serie A is a massive achievement. Whereas when Real don't win the league, and Barcelona and Messi do win the league, you pretend that domestic football doesn't matter, and the only thing that matters is the Champions League.
If Juventus had never signed Ronaldo and kept Higuain, they would be performing exactly the same as they are now. The reason Real are struggling is not because they've lost Ronaldo, it's because their team is over-the-hill and unmotivated, they haven't refreshed the squad, and they've got a crap defence.
However, they weren't a great team last season with Ronaldo, quite obviously, as they completely failed in domestic football.
If it makes you happy to believe otherwise, and believe that Juventus are a good team because of Ronaldo, and Real were a great team last season, then be my guest.
