Emma Raducanu has admitted she wasn’t at her best as she lost in straight sets to Ukrainian Marta Kostyuk at the Transylvanian Open in Romania on Friday.

“I knew it was going to be tough,” Raducanu said.

“I wasn’t physically feeling 100 per cent and was quite tired and lethargic today. Sometimes you have days where you don’t feel your best.

“I knew straight away today, when I was trying to practice I was very limited in what I could do.

“I wanted to go out there on the court and try my best and see if it would go better, but I couldn’t get it going unfortunately.

“I think it’s just the last six months. I have experienced a lot. I am still adapting to the fast-paced life of the tour and am still very new to it, so it’s still going to take me some time to adjust.

“It’s just disappointing that you have these days. It’s not a nice feeling to have. But you just need to move on from it and brush it off. I’ll be back in another tournament soon.”
