Stefanos Tsitsipas and Daniil Medvedev have not seen eye-to-eye since their stormy clash in Miami in 2018 but with the pair set to meet in Friday's Australian Open semi-final it appears there is growing respect between the two.
Sparks flew when they met for the first time on the ATP Tour in Miami, with Medvedev confronting the Greek over his on-court conduct.
Tsitsipas stirred the pot in 2019 when he described the Russian's playing style as "boring" but that is not the term he would use now.
"Might have said in the past that he plays boring, but I don't really think he plays boring," Tsitsipas said. "He's in very good shape, playing good tennis, playing accurate, playing simple."
Earlier this week, Medvedev said Tsitsipas had improved physically and he would be no pushover if a match went the distance.
"I think he's improving physically because maybe two years ago could say, yeah, out of five sets it's maybe not bad to play him," Medvedev said. "I don't think it's the case right now."
Medvedev was proven right in the quarter-finals, with Tsitsipas digging deep to recover from two sets down and pull off an astonishing comeback victory over second seed Rafa Nadal.
Tsitsipas was denied by Nadal and Novak Djokovic in his previous two Grand Slam semi-final appearances but Medvedev knows what it takes to reach a final, getting to the decider at the 2019 U.S. Open before losing to Nadal.
The Russian fourth seed has won 19 consecutive matches dating back to the Paris Masters in November and is in no mood to stop now.
"The best feeling is when you win matches, so the more you win, the more you win in a row, the more it's better as a feeling," he said.
"Hopefully I can continue it for at least two matches."
