When Ronaldo had a good team around him, he won more than when Messi had the best team ever around him.
And when Ronaldo had a decent team around him, he won more than when Messi had a better than decent team around him.
Madrid deserved the 2012 Champions League much more than in 2016, that's luck playing its part and evening itself out through the years. Nothing to do with Modric or Kroos.
Missed this yesterday. So in your opinion:
Ronaldo wins more with the best teammates (by more you mean an extra UCL? and less cups/leagues?) so Ronaldo is the superior player.
Real Madrid win more with better players (Kroos, Modric, Carvajal, Casemiro, Isco, James, Bale) instead of the old guard (Xabi, Khedira, Özil, Di Maria, Arbeloa, Diarra, Albiol) but it's all down to luck.
