For British fans, given the World Cup results, Andy Murray's crash out of Wimbledon, and the minimal numbers of British champs selected for the Tour line up, this has turned out to be the 'anti-year' in British sport, the opposite of 2012.
Federer turns 33 next month, it's hardly time to be writing of retirement. The Fed Express will still be running and calling at its usual stops for years to come... He is not done winning grand slams. And those who write him off are more than just premature, they risk looking like idiots.
Djokovic has apparently turned to Federer, the father of two sets of twins, for some advice on how to manage the relationship of being a husband/father and world-class tennis player and who has now become world No 1.
Djokovic slipped a number of times - he took a tumble, shook it off and got back up. Federer's cool demeanor is majestic - the man is almost completely unflappable...

In tennis, if players turned sour after losing a match, they only lose their sportsmanship and credit. They let only themselves down. This is the same whether they lose, or they win. Nothing is to be gained from boasting in a win, or blaming others for a loss. The same goes for life.

When I was seven years old my dad introduced me to a game called tennis. I'm now 40 years old, still playing, learning and enjoying it. I'm by no means on a par with Andy Murray, but do share similar energy, enthusiasm, determination and commitment.
Andy Murray won the first set of the 2013 Australian Open, but then went on to lose the final to Novak Djokovic. The match demonstrates that at this level of the game, it is mental toughness which determines the victor, not superior technical skill.
