"Wilander: Novak Slam The Greatest Mats Wilander, the 1982, ‘85, ‘88 champion, believes that if Djokovic were to hold all four major titles at the same time by lifting his first trophy on Parisian clay it would be equal to anything achieved in the sport’s history. “You’d have to put him straight up there with a [Bjorn] Borg, maybe Rafa [Nadal] too, just as an achievement. You couldn’t put him past Roger,” stated Wilander. Wilander said a Djokovic non-calendar year Slam would “easily” equal Laver’s 1969 calendar year feat. “It doesn’t matter. It doesn’t make any difference (if it’s the same year). The thing about Rod Laver, three of them were on grass - so in that way, you can put four in a row and the calendar Grand Slam (together). They’re the same because they only played on two surfaces back then. Four in a row is what matters really.” http://www.atpworldtour.com/News/Tennis/2012/06/23/Roland-Garros-Tuesday2-Diary.aspx Watson: I say surprise as I'd have thought he'd have put the 4 in succession alongside anything Roger did, but I stand corrected as he doesn't seem to think that. I agree with him in that it not being in the same year makes no difference, and that it should be regarded as highly as Laver's, if Novak does it.
