Just as his fans are gazing adoringly at photos of Roger, Mirka, and assorted family members on a luxury yacht in the Mediterranean, he isÃ¢â‚¬â€metaphoricallyÃ¢â‚¬â€ planning that between-the-legs killer of a shot that takes the wind right out of their sails.
For Federer, with his usual economy and via the usual medium of his own website, has made an unexpected announcement. Addressed Ã¢â‚¬Å“Dear Fans,Ã¢â‚¬Â it says:
Ã¢â‚¬Å“I’ve been looking to add someone to my team and I’ve decided to spend some days with Paul Annacone.
“As Paul winds down his responsibilities working for the Lawn Tennis Association, we will explore our relationship through this test period.
“Paul will work alongside my existing team and I am excited to learn from his experiences. Ã¢â‚¬Â¨See you soon, Roger.Ã¢â‚¬Â
He has, of course, done this before.
Last spring, it was briefly announcedÃ¢â‚¬â€neatly timed between news of impending fatherhood and his weddingÃ¢â‚¬â€that he was exploring an arrangement with Darren Cahill.
The year before, it was a part-time relationship with JosÃƒÂ© Higueras who remained Ã¢â‚¬Ëœon trialÃ¢â‚¬â„¢ from Estoril through to the SpaniardÃ¢â‚¬â„¢s migration to the USA to coach its elite players.
In a nice mirroring of the Cahill storyÃ¢â‚¬â€which broke just as Cahill retired as Assistant Coach to the Australian Davis Cup TeamÃ¢â‚¬â€Annacone is to leave his post as coach for menÃ¢â‚¬â„¢s tennis and the GB Davis Cup team.Ã¢â‚¬Â¨Ã¢â‚¬Â¨
AnnaconeÃ¢â‚¬â„¢s contract with the LTA does not end until November, but this latest development, on the back of the resignation of John Lloyd and the appointment of Leon Smith as the new Davis Cup coach, suggests that he will not be hanging around the LTA for very much longer.
Most interesting, however, is what the new relationship with Federer tells us about the ambitions of Federer himself. Ã¢â‚¬Â¨Ã¢â‚¬Â¨The wording of the announcement suggests that this is not a formal Ã¢â‚¬Ëœcoach-and-playerÃ¢â‚¬â„¢ agreement.
It is an exploration, very much as the Higueras relationship was an exploration of how to pick a clay-court expertÃ¢â‚¬â„¢s brain and develop the tools to win the French Open.
So it is worth looking at the strengths and skills of Annacone to find a clue to the Federer mindset.
The American was himself a serve-and-volley exponent, a player who would attack the net even on his opponentÃ¢â‚¬â„¢s serve. He won just three singles titles but was a highly successful doubles player. Indeed he won the Australian Open doubles title in 1985.
Ã¢â‚¬Â¨Ã¢â‚¬Â¨As if that was not clue enough, one needs only to glance at Annacone’s CV between 1995 and 2002. He was full-time coach to Pete Sampras, one of the greatest serve-and-volley exponents of recent years. And Annacone subsequently moved on to coach Tim Henman, another excellent serve-and-volley player. Ã¢â‚¬Â¨
Federer has always shown a willingness to approach the netÃ¢â‚¬â€even in beating the great Sampras himself in their only meeting. That was Wimbledon 2001, a glorious five-set battle of champion-versus-challenger. The stats on that day were remarkably similar, not least the tally of aces, 26 to 25. Ã¢â‚¬Â¨
And Federer has constantly claimed Sampras, Stefan Edberg, and Boris Becker as his idols. The common thread in all this, as if it needed spelling out, is an enthusiasm and a talent for attacking the net. Ã¢â‚¬Â¨
Federer has shown more enthusiasm for all-court play in the last year or so, and a willingness to try new game plans: the drop-shot on clay and the wide swinging serve from the deuce court on hard and grass courts both spring to mind. He also has touch to die for and the light and fast footwork necessary to reach the net and make quick adjustments.
The added input from such an experienced tutor as Annacone could add the variety and tactical edge that have thus far stopped Federer from being a truly great serve-and-volley exponent.
This all throws up the thrilling prospect of a fully-rounded, fully-committed, full-blooded net-attacker: Federer as the complete tennis-player.Ã¢â‚¬Â¨
One big question remains. Just how far can Federer put himself into a new pair of hands? Annacone will have to be both tough and velvet-gloved to handle such a self-contained athlete.
But if it works, it shows that Federer believes his game still has some evolving and improving to do.
It also shows he is deadly serious about staying at the top of tennis for a little while longer, and for that we should all be mighty grateful.
