Nick Kyrgios has seemingly angered fans over in Germany after telling a ball boy to run properly during a match.
The Aussie tennis player was competing against Hubert Hurkacz in the semi-final of the Halle Open when he accused a young kid of putting him off with their strides.
Claiming he was being distracted, Kyrgios then told the ball boy to correct their running technique – a move which has plenty of people talking online.

During the second set, the ball boy tripped while picking up Kyrgios' first-serve fault.
In his second attempt, one of Kyrgios' baseline forehands was given out by the umpire, which is when the Australian star turned his attention to the ball boy.
"You just put me off. Run properly, please," he said.
It'll undoubtedly go down as one of his most bizarre complaints to date.
Kyrgios want on to lose 4-6, 7-6, 7-6 to the Polish world No.12 before beating Daniil Medvedev in the final of the tournament.

The exchange between Kyrgios and the young lad comes not long after was involved in a seperate incident with an ATP supervisor.
During his round of 16 clash with Stefanos Tsitsipas, Kyrgios smashed a racquet on the court after losing the opening set.
And after being given a second warning for taking too long to reset between points, Kyrgios began engaging in a war-of-words with both the chair umpire and eventually the supervisor.
But despite all that, on the court, the Aussie has been in impressive form.
