What??? Only season where Madrid didn't have a worse squad than Barcelona they won the league and the Champions League. One season where Madrid didn't have a worse squad than Barcelona. ONE.
Ronaldo was 9 years in Spain with Messi, played 8 of the 9 years with a worse team around him and won more than him.
The only reason Barca may have had a better squad 8 out of 9 seasons is called Messi. If you take both Cristiano and Messi out of the equation, Real had a better squad after Neymar left until this season. That's only my opinion, of course, just like what you so conveniently presented as a fact in the cited post is yours.
Maybe we should also consider the managers both had. Cristiano never had to cope with guys like Valverde or Martino.
