Andy Murray suffered tremendously at the hands of Roger Federer at the ATP World Tour Finals last week and, one week on, he has faced a barrage from his fans on Twitter during the Davis Cup Final.
The Briton took to the social media site whilst Federer was securing Switzerland's first ever Davis Cup final with a decisive singles rubber victory over Richard Gasquet on Sunday.
In an initial tweet, Murray noted: "Amazing how long a couple of days is in sport..." The message appeared to be in reference to Federer's performance turnaround over the weekend, as he started the match with a straight sets loss to Gael Monfils on Friday.
However, for whatever reason, some fans of the 17-time Grand Slam champion decided to translate Murray's post as criticism of their idol. The British number one replied to three fans who seemed very upset with him indeed.
One particular tweeter cranked things up a notch by suggesting that Murray should shove a racquet up into one of his personal areas - I'll say no more apart from that's not very nice at all.
Having withstood enough abuse and questioning, the 27-year-old cleared things up - not that he should have needed to - by explaining his earlier comments: 'Federer struggled on Friday and was fantastic today hence a lot can change in a couple of days, please relax fedfans.'
Of course Murray is no stranger to some of the poison that darts around on Twitter at regular intervals. Just a few months ago the Scottish-born start received plenty of negative feedback over his decision to support Scotland's exit from the United Kingdom in the recent referendum. The police were even forced to intervene at one point with some sickening messages.
Though, to be fair, he isn't the only person recently to fall foul of some tennis fans - Novak Djokovic had a heated moment with the London crowd on his way to a fourth ATP Finals title.
The Serb, as he had been doing all week, was dominating proceedings, this time in his semi-final encounter with Kei Nishikori, when the crowd started cheering against the world no.1 hoping for a more even contest.
As the O2 Arena crowd applauded a double fault of Djokovic, the seven-time Grand Slam champion sarcastically applauded towards the stands and shook his head in disgust.
While Djokovic was unhappy with Nishikori's fans, it was perhaps lucky that the same scenario wasn't played out with Federer - he has one of the biggest followings in the sport.
In terms of Facebook fans, Federer boasts an impressive 14,750,000+ 'likes' to Djokovic's 5,500,000+. However, there are still two stars who have bigger followings on the site.
Rafael Nadal has just shy of 15 million, but Maria Sharapova is the most popular person in the sport - she has over 15 million.
