The 63rd-ranked Ruud went out last night in the Paris Grand Tournament. Frenchman Adrian Mannarino won 6-4.6-2 in the first round and will now face Rafael Nadal in the second round.

Afterwards, Ruud received questions about his strained relationship with the problem child 30-rated Nick Kyrgios, something that originated in a match in Rome in mid-May, which ended with the Australian being disputed. Ruud then wanted to see him suspended for a long time and repeated the criticism last week in an interview:

- He was completely crazy when I met him. It is his problem that he is an idiot on the course, Ruud told the Swedish site Tennisportalen.se and the interview was also translated into English.

Kyrgios is currently suspended on the ATP tour

So did Kyrgios, who is currently suspended from the ATP tour for four months after repeated disciplined wrongdoing, very upset and he answered Ruud in sharp words on Twitter.

“Hi Casper Ruud, next time you speak, I would appreciate it if you said it to me face to face. I'm pretty sure you wouldn't be as cocky then. Until then, I'd rather watch when paint dries than when you play tennis, you're so boring, "Kyrgios wrote.

Now Ruud wants to stop the pie throwing.

- I have talked clearly about Kyrgios no matter what he will say. I will not comment on anything more about him, Ruud tells Norwegian NTB.
