They did for a while. MSN is much better though. Most people just look at goals when comparing, but it's much more than that. For example, the Henry - Eto'o - Messi trio scored 100+ goals, but under Guardiola they had the best midfield in the world, with Busquets, Xavi and Iniesta all in the best shape of their lives. Now Barcelona's midfield pretty much pass the ball to Messi and the three forwards do the rest all by themselves. No matter if Ronaldo, Benzema and Higuain scored a similar amount of goals, MSN is better. I'd be willing to bet a good amount of money that if you used goals + assists instead of just goals, MSN would be way ahead of the Real Madrid trio.
