After winning the Australian Open, still there are Wimbledon, French Open and US Open to be won by Djokovic to attain the Grand Slam title during the calendar year. Though among the current players Djokovic enjoys a superiority, that superiority is not by a wide scale. Federer may make a comeback in any of the event. Nadal or Murray may surprise him. It is not an easy thing to attain the grand slam and the possibilities are slender. It should be noted that nobody is regarding Djokovic with the same respect as players like Boris Becker, Jimmy Connors, John McEnroe, Bjorn Borg, Roger Federer, Peter Sampras etc. Maybe, Djokovic can be viewed in the same category as Agassi. Nothing more than that. Because of the ten percent decline in the calibre and withstanding ability of Federer and Nadal, Djokovic could rule as the king.
