Nick Kyrgios, who crashed out of Wimbledon in the fourth round on Monday against Andy Murray, is once again in the limelight for all the wrong reasons, making statements like "I don't love this sport" and getting annoyed with the press after his defeat.
Number two seed Murray defeated Kyrgios 7-5, 6-1, 6-4 in a match where the Australian played well initially, but was not the same player for the remaining two sets, where he did not seem as committed to the match as it went on.
In an interview with the press after his defeat, Kyrgios said he was motivated to play at times and then seemed to lose interest in staying focused and motivated.

"I don't love this sport," said Kyrgios. "But I don't know what else to do without it.
"One week, I'm pretty motivated to train and play. Another week, I'll just not do anything. I don't really know a coach who would be down for that one.
"I'm just a little soft still. I think when things get tough, I'm a little bit soft. I've got experience, but it comes down to laying it all out there and competing for a long time. I didn't do that here at all.
"To be honest, I woke up this morning [Monday] and played computer games. Is that the greatest preparation? I don't know. But it was fun.
"Every time I come here, I lose to good players. But it's just disappointing. I don't know. I just want to do better."
Things got heated when the 21-year-old was asked by a reporter if he could "just walk away from the sport". Kyrgios responded saying, "diabolical question" adding: "I just lost in the fourth round, I didn't lose in qualifying. I feel like I am doing alright."
The fiery Australian faced criticism from former Wimbledon champions and greats of the game John McEnroe and Pat Cash, who were not impressed by the way Kyrgios seemed to just throw the match away instead of showing fighting spirit after losing the opening set.
In an interview with the BBC, McEnroe said: "Disappointment would be an understatement in describing Kyrgios' effort, particularly as the match went on.

"He played a horrible point at 30-40 in the first set to lose it but that means you've got to dig in and show, 'I'm going to play even harder and I want it even more', instead of just throwing the second set away.
"He's got to look in the mirror if he wants to become a top player and win Slams now. Certainly based on that performance I've become more concerned."
Cash, the 1987 Wimbledon winner, was similar to McEnroe in his criticism when questioning his countryman's commitment on court going as far as saying fans courtside were "a bit short-changed".
"Sometimes you think about Nick and think he needs some rewiring. I don't think he is trying sometimes, there's no doubt about it, but that's the way he plays.
"People are watching that match and think, 'What's going on?' They might come away from it feeling a bit short-changed."
