Emma Raducanu has shown off her Spanish language skills as she prepares for the round of 16 at the Madrid Open. 

Raducanu secured a 6-2, 6-1 over Marta Kostyuk of Ukraine in the second round of the WTA 1000 event. 

The 19-year-old has struggled to put together a run of form since her improbable victory at the US Open in September, but she seems to have now found her feet at clay court tournaments. 

After winning back-to-back matches just once in the six months following her US Open title, Raducanu has now done so twice in as many weeks.

"I'm definitely very happy with my performance,” she said. “Marta is a great opponent… and I knew it was always going to be a really tough battle. I went out there trying to be really aggressive, and it definitely paid off.

"It's my first clay-court season and I'm really enjoying it. Madrid is such a cool city and it's got such a great vibe about it, so I definitely want to try and stay here for as long as possible."

Raducanu is enjoying Madrid so much that she has been trying out her Spanish. The British star ended her post-match interview with “gracias a todos”, meaning “thanks to everyone”.

It is not the first time Raducanu has impressed with her language skills. Her mother was born in China and her father grew up in Romania, meaning she is fluent in the language of both countries. 

The US Open champion has often shown off her trilingualism, once addressing her Chinese fanbase on Weibo in perfect Mandarin. She also gave a post-match interview at the Transylvania Open in Romanian.

Raducanu seems to have shaken off a number of fitness issues which blighted her performance after the US Open. 

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.

The blisters then reappeared to hamper Raducanu at the Billie Jean King Cup, but she quickly put this behind her to embark on an impressive run to the Stuttgart Open semi-finals. 

Raducanu’s next challenge is to find a coach. She recently parted ways with Torben Beltz after just five months of working together.

“Torben is a very great guy,” she said. “I really enjoyed my time with him on and off the court.

“He is one of the nicest people I’ve met so it was a tough one to split with someone like that, but I feel like right now I’m very comfortable with my current training and how I’m training.”

Raducanu's next match at the Madrid Open will be against another Ukrainian tennis star, Anhelina Kalinina.
