Federer would have won 4 in a row had he won any of the matches against Nadal from 2005-07 Rolland Garros.I mean not really. Federer was a single win away from doing exactly the same thing on 2 different occasions, if Djokovic had gone through the single obstacle Federer had to go through again and again en route to doing it then maybe, but as he simply benefited from being in peak form for the couple of years that Nadal fell off I wouldn't say it's all that one of a kind achievement. Consider also that Federer might have won 4 in a row if not for Roland Garros 2005, he might also have won 4 in a row if not for W08/AO9, he lost on every single one of these occasions to the one dude.
But the one match he closely missed winning was US 2009 final against del potro. So many chances to go 2 sets love and win the match. Then he would have won 4 in a row.
Similarly novak Djokovic also missed 4 in a row in 2011 French, 2012 French and also 2015 French. But he was never very close to winning any of these matches
