Wimbledon men’s last 16: Murray in battle with colossus Karlovic

Next up, the Swiss star (11/2 for an unprecedented eighth title here) faces perhaps an easier challenge against Spain’s Bautista Agut (9/1), who has lost both his meetings with Federer (heavy 1/20 odds-on favourite).

The 17-time Grand Slam winner has never dropped a set against his upcoming opponent, so is 2/5 to triumph 3-0.

Tomas Berdych v Gilles Simon

Both Berdych and Simon, the latter in particular, had to come through tough tests in the last round, against Pablo Andujar and Gael Monfils respectively, and these battlers could be set for another epic.

In 10 head-to-heads, Frenchman Simon has won six, so is a very tempting 2/1 shout to beat Berdych (2/5), but the duo have never met on grass before.

This is a potential five-setter, so take odds of 11/2 for the Czech, runner-up here in 2010, to triumph 3-2.

Vasek Pospisil v Viktor Troicki

Neither Pospisil (9/4) nor Troicki (4/11) will be that popular with the crowd, after knocking out home hope James Ward and dreadlocked fan favourite Dustin Brown, Rafael Nadal’s conqueror, in the third round.

This will be the pair’s first ever meeting, and this could go the distance too, after Canadian Pospisil has already had to come through two five-setters, while Serb Troicki’s have all gone to four.

Troicki has a great price of 9/2 to win 3-2 here.
