When I was growing up, I thought Pete Sampras was already the compleat tennis player, but on hindsight, you get to appreciate more how compleat some of this generations players are - Roger Federer, Rafael Nadal and Novak Djokovic, because, not only can they be dominant in one surface, they also make those little adjustments to their game, to make them deadly in the other surfaces.
And Rafael Nadal is testament to that. Like Guga, Nadal could have easily not bothered about the other grand slam titles and just decimate everyone in the French Open on clay, but he decided to tweak his game, so much so that in a hardcourt, which he says is a surface he is not really good at, a newbie in the grand slam finals department is the only one blocking him from yet, another US Open title.
And although talented players like Kevin Anderson of South Africa, have finally put themselves on the world stage of tennis, this year, has really been a master class of men's tennis from two of its most legendary players - Roger Federer and Rafael Nadal.
If a pundit told me exactly a year ago that Federer and Nadal would be dominant in the grand slams of 2017, my right eyebrow would rise an inch higher and give him (or her) a look of incredulity.
Yet, it has happened, and the possibility that two of the grand slam titles of 2017 will go to Rafa, as it did to Roger, is now a strong possibility.
Of course, we would love to see Kevin do well in the final, but the way Nadal demolished del Potro in their semi's, you can really see that Rafa will bulldoze you over if he can.
