Grand Slam titles are all well and good, but within tennis itself the year-end world number one is perhaps the most coveted honour of them all.
It means you haven’t just had a good run of form – you’ve had a good year.
It means you haven’t just had a dream Grand Slam run, it means you’ve had three or four.
It means you haven’t just had a favourable Grand Slam draw – you’ve gone the distance and earned it, again and again.
There is, indeed, an argument put forward by many that number of year-end world number ones is that most significant thing to win as it’s harder to be good for 52 two weeks than it is for two weeks ,which is required to win a Grand Slam.
There can be only two every year, so how many tennis year-end world number ones can you name?
Good luck with this one in the meantime, and don’t forget to tweet us your scores @tennisbuzzblog.
