Beef! Prime cut, medium-rare, premium quality beef! As any fule no, sport is much more interesting when the participants don’t actually like each other, or if there is some sort of animosity or friction between the two. Tiger Woods v Sergio Garcia, Roy Keane v Patrick Vieira, Roger Clemens v Mike Piazza - wonderful, tender, delicious beef.
Now, Andy Murray v Viktor Troicki might not quite be up there with the beefiest of the beef, but there’s still a little meat between the two. Maybe some paper-thin carpaccio. But still, there’s history between the two, largely stemming from when Murray criticised his opponent for refusing to take a blood test.
