Emma Raducanu feared that there would be "bad blood" with Andy Murray after withdrawing from the mixed doubles at Wimbledon.

Murray, who retired from professional tennis after the Paris Olympics, was due to feature alongside Raducanu at the All England Club last year.

However, on the morning of their first-round clash against Marcelo Arevalo and Shuai Zhang, Raducanu pulled out of the contest, citing soreness in her wrist.

Her withdrawal saw Murray denied a final match at Wimbledon, a stadium where he claimed two men's singles grand slam titles in 2013 and 2016.

The Scot was known to be hugely disappointed about the outcome, overshadowing Raducanu's run to the fourth round, her best at a grand slam since she won the US Open.

But after beating Amanda Anisimova in straight sets at the Australian Open, setting up a third round tie against Iga Swiatek, Raducanu was happy to be congratulated by Murray on her victory.

"Afterwards, I sent him a long message basically apologising if I caused any trouble. I guess, at Wimbledon, that's definitely the last thing I want," Raducanu told reporters.

"He's someone that I've grown up looking up to, and I don't want any bad blood or harsh feelings with him. I sent him a long message, and he took it really well and responded saying he was disappointed, but he understood.

"We're fine now. We walk past each other and say, 'hello', 'well done'. It's obviously really cool seeing him with Novak (Djokovic) here as well."

Raducanu could be seen laughing on the court during her clash with Anisimova, a rare sight having struggled with several injury problems in recent seasons.

The 22-year-old has become used to a lot of noise swirling around since her New York breakthrough, but said she was confident of a good run in Melbourne this year.

"Yeah, I think this year I'm just approaching it quite holistically, I would say, in the sense of just having good people around me, having a positive outlook," she said to reporters.

"You know, anything that's not necessarily serving me, I'm just pretty savage in terms of just prioritising myself and focusing.

"Anything that wants to try and affect that, I don't have time for it. No hate. I just don't want to kind of let that in."

Raducanu, however, has had to deal with a niggling back problem at this year's Australian Open, and received treatment during the second set against Anisimova.

"I haven't fully investigated it yet," Raducanu added. "I think it's almost to be expected when you haven't played a match in so long, and then to have two really physical ones.

"I think small niggles are going to come up here and there. I'm just hoping that it is that.

"I was able to push past some pain today, but I'm going to just try and recover as best as possible over the next day."
