Federer

Federer's bent for dullness and propriety at least allows us to appreciate his gifts without tabloid distractions.
Better, surely, that we can admire the poise and balance of a game that has no equal than dwell on the man's private life, which is, by all accounts, about as exciting as that of any nappy-changing Swiss dad who parts his hair in the middle.

Yet tennis, like the rest of modern sport, has always craved "personalities", and the genteel racket game has had its moments.
Martin Amis, writing in the New Yorker in 1994, made it clear he abhorred the vulgarity of John McEnroe, Ilie Nastase, Jimmy Connors and, to a lesser extent, Andre Agassi.

Those extroverts (he preferred the word assholes) were, he said, the polar opposites of Rod Laver, Ken Rosewall and Arthur Ashe, whom he described as "dynamic and exemplary figures". Amis reckoned they "didn't need personality because they had character".
