Nick Kyrgios has hit out at officials once again at Wimbledon, after an out call was overruled while he was serving at 5-5 against Stefanos Tsitsipas.

The Aussie's x-rated rant for a "new" referee comes after he was slapped with a £8,200 fine for his first-round match in which he called a linesperson a "snitch" an spat towards a spectator. 

Kyrgios was serving at 5-5 in the first set of his match against the fourth seed when one of his shots was called out but overruled by the umpire. 

And the world No 40 was quick to hit out at the officials days after he was fined for calling a linesperson a "snitch" in his match against Paul Jubb, where he also claimed the lines people were too "old" to see properly. 

"It's 5-5 all bro, it's 5-5 all bro. So get a new one, get a new umpire," he ranted. "Bro, you're supposed to make the right call, you don't get credit unless you make the right call. 

You just say sorry and it's all good? It's f***ing... why don't you just get a new referee? He's got one line to call bro." 

The 27-year-old was also unhappy that there appeared to be a mistake made in "every match" as he continued his tirade. "Every match there's a mistake, and we just have to deal with it? Every match. Why you scared, why are you hesitating, at 5-5 all?" 

Kyrgios had already been fined for complaining about a lines judge on the centre service line in the first set of his five-set victory over British wildcard Jubb in round one. 

"Has one person today come to see her speak? Why is she doing that? Not one person in the stadium has come to watch her do anything. I know you've [the umpire] got fans but she's got none. 

What she just seflishly walks to you in the middle of the game because she's a snitch? Come on now," he ranted to the umpire at the time.

The former quarter-finalist at SW19 was asked if he spat at the end of the match in his press conference on Tuesday and said: "Of one of the people disrespecting me? Yes."
