Andy Murray Wimbledon 2015
Andy Murray will hope that smile remains intact during his fourth round match against Ivo Karlovic at WimbledonReuters

Ivo Karlovic is the next, considerably big, hurdle in the Wimbledon title path for Andy Murray, with this fourth round match at Centre Court promising one thing for certain – plenty of aces.

Karlovic is a bit of an ace machine, having recently broken the record for a three-set match by firing in 45 of those bombs against Tomas Berdych in Halle.

So, Murray knows what to expect from this fourth round match against the big Croatian.

"Obviously he has served extremely well this tournament," said the number three seed of Karlovic. "A couple matches here where he served over 40 aces. In Halle, as well, he served I think the record for three sets with his match with Berdych.

"[It will be an] extremely tough match. I'll need to be very sharp on my returns and try and find a way to get as many of his serves back in play as possible and see what happens.

"But it's obviously a very, very tricky match."

Murray, who beat Andreas Seppi in four sets in the third round, has a good record against Karlovic, having never lost to the No.23 seed, and with the Brit playing some really good tennis at Wimbledon, with a partisan crowd to support him as well, it will be Karlovic who will need to produce some seriously outstanding tennis to cause a major upset.

"I feel like I'm playing very well," Murray added. "There's obviously like that period in the third set [against Seppi] that wasn't great. Then also against [Mikhail] Kukushkin, when I was up 5 3, then there was like a 15-minute period there where my level dropped.

"But the rest of the time it's been very good. I just need to try to cut out those periods in the matches. Rather than have a 15 or 20 minute lull, make it a five or six minute lull. Where you can't play at the highest level, you know, for three, four hours. You're always going to have little dips. But maybe they've been a bit too long this week."

There will be moments in this match where Murray will find it difficult to win even a single point off the Karlovic serve. It is those moments that Karlovic, who became the oldest player, at 36, since Niki Pilic in 1976, to make it to the last 16 of Wimbledon, will need to take advantage to crank up the pressure on Murray and see if a crack or two come to the fore.

"[I have never beaten Murray], so now it's an opportunity to," Karlovic said. "I feel good. I like what I do. I'm having fun. So I don't know how it's going to be. I have a chance, for sure."

If Karlovic plays like he did against Jo-Wilfried Tsonga, where he beat the Frenchman in four sets, three of which went to tie-breaks, all won by the Croatian, then he will certainly test Murray; how much, only time will tell.
