After his four-set loss to Great Britain's Andy Murray at Wimbledon, Croatian Ivo Karlovic says he was cheated in the match by linesmen.

"Foot-faults. I don't know what to say, but it was a little bit outrageous," Karlovic said. "In my whole life, ever since I was eight years old, whole life I didn't do this many foot-fault. It was like 11. It was never called when it was like 30-Love or 40-Love. It was always when it was 30-All or in a tiebreak. I mean, what is this? Is it Davis Cup or is it Wimbledon? After this match, the whole credibility of this tournament went down for me... But I don't do them, foot-faults...

"Then like after I don't know how many, I stand a little bit back so they cannot call. They still did it, called. So it was outrageous, outrageous. It's Wimbledon, Centre Court, and they do this. I mean, this is BS. I feel cheated. On a Grand Slam, Centre Court...

"Right now I'm angry about it, little bit pissed, because I don't expect it here. Even though it is against English guy who they always want to win, but I don't expect it here."

Murray responded: "That's very tough to question the integrity of Wimbledon. I mean, it's got a lot of history, a lot of tradition. There's been hundreds of thousands of matches played here over the years. I've never heard that before. But I need to see the videos. If there was 11 foot-faults called against him and every one was incorrect, then that's completely wrong and unfair. But for it to happen that many times, you would think there would have been a number of fairly obvious foot-faults, because you don't really see them called that much nowadays. Very rare. If it turns out that he wasn't foot-faulting, if I was him, I'd be very, very disappointed."
