2007 Nadal > 11, 13 Nadal by a significant distance. LOLOLLLYou think the 2008, 2010, 2011, 2012, 2013 version of Nadal couldn't beat the 2005-07 Nadal? lol He was stronger then.
2007 Nadal > 10 Nadal as well.
2007 Nadal and 12 Nadal are on similar level, give or take.
Anyways 10 Nadal is not so relevant here as neither fed or djokovic faced him at RG that year.
2006 Nadal surely better than 11 Nadal and similar level to 2013 Nadal
ditto for 2005 Nadal
Anyone who thinks 11 Nadal isn't the worst Nadal on clay/at RG when talking about period from 05-13 doesn't know wtf he/she is talking about. saying 07 Nadal worse than 11 Nadal in particular is just asking to be laughed at.
