And how often does Ronaldo do that? once in every 10 games? I only remember him doing that once before against us and that was in the final of the copa del rey(and even in that one he only really got past 1 player). Otherwise most of the times he has the ball it's on the counter where he only has to face 1 defender. Where as with Messi it's the other way around, most of the times has to face 3-4 and once in every 10 game does he get to face only 1 defender...
And the few times that Ronaldo do those kind of runs, its on the counters. Meaning that every defender are out of position, making it easier to get past players. While Messi has to do those runs when a team has parked 10 player inside their own half ergo it's harder for Messi to do them..
I mean, just look what Messi can do by himself when he has the opportunity to counter
But even then its very hard to get past that many defender and it would be pretty stupid for him to do those runs every time, for the simple fact that he would be losing alot more balls than he do now and as you know, he already loses the ball more than any other player because he already tries to dribble more than any other players..
