Emma Raducanu was left in hysterics after accidentally swearing in Italian during a TV interview.

The 19-year-old is currently in Rome for the Italian Open, with her opening match against Bianca Andreescu scheduled for this evening.

Raducanu was being interviewed by SuperTennis TV when she was asked if she had learned any Italian yet.

She replied: “Err… I did… like, que cazzo?" The phrase roughly translates as “What the f***”, which soon became apparent when the interviewer let out a surprised gasp.

"Is that a bad word?" Raducanu said, with the interviewer replying: "A little bit."

Raducanu then added: "My friend taught me that word. Cut that one. What does it mean?"

When the interviewer said she would tell Raducanu the meaning of the phrase at the end of the interview, the British tennis star expressed her disbelief about swearing on camera before bursting into laughter.

"Oh my god, erm… Bongiorno,” Raducanu said. “I can't believe I just fully swore on camera!"

Raducanu is normally exemplary with her language skills – she is fluent in Mandarin and Romanian, and has given a post-match interview in the latter.

She also showed off her Spanish skills in a post-match interview at the Madrid Open.

Raducanu has struggled to overcome a number of fitness issues since her improbable victory at the US Open in September.

Severe blistering on her right hand led to defeat in the second round of the Australian Open. She then retired from her first-round match at the Guadalajara Open with a hip injury, and blamed a loss at the Miami Open on a stiff back.

Radacanu also experienced back problems at the Madrid Open, subsequently losing to Ukraine’s Anhelina Kalinina in the third round.

“I think it’s just coming from a lot of intensity and overload,” Raducanu said, in advance of her clash against Andreescu at the Italian Open.

“My back, I’m managing it. Like it’s fine. But it’s just trying to adapt again to the long matches, to the intensity.

“I think that all of the small niggles I’m getting are all related and connected to each other, when something is overcompensating perhaps. Yeah, we’ll see.”

Raducanu has impressed during the clay-court season, particularly with her performances at the Madrid Open, but she revealed she felt the surface at the Italian Open would be completely different.

“I think here is completely opposite,” she said. “It’s quite heavy and slow, so there’s going to be a lot longer points.

"It will be interesting to see what the differences are. But I can already feel them on the court tennis-wise."
