Andrey Rublev was made to work incredibly hard by Daniil Medvedev at the Australian Open and he has vowed to keep working to reach his compatriot's level.
Rublev reached his fourth Grand Slam quarterfinal in Melbourne, but he is still yet to win a set in any of them.
His latest one was more a test of endurance than anything else, though, with Medvedev able to run Rublev incredibly hard in the searing heat, leaving him gasping for air and leaning on the court surroundings between points.
Incredibly, there was one 'brutal' rally of 43 shots, so it is little wonder it started to take its toll on the 23-year-old.
“If we take all the matches that I've played against him, today he played his best level,” said Rublev. “He was playing really well today, and he deserved to win because he was really better than me.
“You need to be focused 100 per cent every point, because as soon as you relax or something, then he will use the opportunity.”
“There were only two turning [points] where I felt [something] could happen.
"At 5-5 in the first set, I had little chances that maybe if I would have broken him, it could be different story… and in the second set at 3-3, the break point that I had could [also] change [the match].
"Because I had an easy, easy ball to finish [the point] and I didn't make it.
“We're going to play I hope for many, many years, so at least once I think I will have a chance to win.
“Because every time I play him — at the  US Open I had chances, I had set points. Here, I had break points… One day it's going to be my day.”
