Nitto ATP Finals: Stefanos Tsitsipas is attacked for "sore loser" comments at the ATP Finals

Rublev fought hard to advance to the semifinals of the season-ending tournament after shelling out a 3-6, 6-3, 6-2 victory in the final group-stage match. 

After winning the first set comprehensively, Tsitsipas ran out of gas in the next few games against a powerful Rublev, who will encounter world number four Casper Ruud.

Tsitsipas' shared his disappointment with the media through the post-match press conference, where he claimed he was the better player among the two. 

The Greek player seemed to undermine the Russian's talent stating Rublev "prevailed with the few tools that he has." Fans immediately criticised Tsitsipas for the comment as the 24-year-old signed off from the remainder of the season.

"It's a shame. I feel like the better player," he said. "I felt like I could do more with the ball today. I felt like I could just be much more creative. I don't even have to say that. I think it's quite obvious."

Tsitsipas believes that his opponent utilised the few tools he had, which worked to his advantage. Social media was outraged at his claim. 

What was Andrey Rublev's answer to Stefanos Tsitsipas?

In his press conference, Andrey Rublev was asked to comment on Tsitsipas' claim about Russia. He brushed them off with relative ease when the reporters explained how the lawsuit could have been a verbal attack on Rublev.

The Russian player was bemused, and it took him a while to make sense of it. However, he calmly acknowledged that he played against a higher-ranked opponent and beat him. "I mean, I don't know if I have a few tools," he shared.

The 25-year-old further laid out a comparison between the two players. Based on shots, he believes his backhand is weaker than the Greeks. 

However, Rublev is confident he has a better forehand than Tsitsipas, who is faster if not a player with a quick serve. "Obviously, he's better player because he's higher ranked and he achieved better results. It's obvious. There is no doubt," he signed off. 

The Russian is making his third appearance at the ATP Finals, having reached the semifinals for the first time. In his previous matches, he defeated compatriot Daniil Medvedev 6-7(7), 6-3, 7-6(7) in a nail-biting encounter. 

He squandered six set points in the first set before conceding in the tiebreaker, but his subsequent comeback was a memorable moment in the tournament. 

Novak Djokovic bested the sixth seed in straight sets before his electrifying victory against Tsitsipas in a winner-takes-all game.
