Diego Schwartzman will face Rafael Nadal in the last-16 of the Australian Open on Sunday.

The Argentine, who’s currently ranked 26th in the world, beat Ukrainian Alexandr Dolgopolov on Friday morning as he reached the fourth round of the tournament for the first time in his career.

Losing the first set on a tie-break, he levelled the match, winning the second, 6-2, before taking the third and fourth set 6-3.

Sunday’s match will be the fourth meeting between them, with the Spaniard winning all three, and Schwartzman yet to win a set.

Despite his 100 percent winning record against him, Nadal says he’s expecting a ‘tough’ match on Sunday, calling him a great player.

Speaking after his win over Amir Dzumhur , he said: “He’s a player that last year had an amazing year, and this year start again playing so well. So already won three matches here, playing again at very high level. He’s a very complete player.

“Being honest, he’s a player that if I don’t play my best, probably I don’t going to win. He’s a player that have all the shots, big control from the baseline, don’t miss much.

“He’s able to change directions easy. He’s a player that already played the quarter-finals in the US Open. He’s already in the fourth round and I need to play my best.”
