Nick Kyrgios, who is currently ranked 37th, said he's the first or 2nd-best tennis player in the world after beating No. 1 Daniil Medvedev

• Nick Kyrgios continued his remarkable form by beating Daniil Medvedev on Wednesday.
• After the win, he said he believes he should be ranked as "one or two" in the world.

Nick Kyrgios claimed his current level of tennis would have him ranked first or second in the world after he beat current world No.1 Daniil Medvedev at the Montreal Masters on Wednesday.

Kyrgios didn't drop a serve as he came from a set behind to beat the Russian 6-7 (1-7), 6-4, 6-2 in the round of 32.

The victory continues a remarkable run of form for the Australian, who finished as the runner-up at Wimbledon last month and earlier this week made tennis history by becoming the first player ever to win the Citi Open men's singles and doubles titles in the same year.

After the victory against Medvedev, Kyrgios was asked by Canadian journalist Arash Madani about what ranking his current form deserves.

The 27-year-old, who is currently ranked 37th, replied: "One or two."

Kyrgios' victory over Medvedev in Montreal was only his second career win over a world No. 1.

The last time he beat the top-ranked men's player was as a teenager at Wimbledon 2014 when he beat Rafael Nadal in the fourth round.

The Aussie said he now aims to keep the the ball "rolling" ahead of this month's US Open.

"I feel confident in my body and my mentality going in to the US Open but at the same time there's so much time between then and now," he said.

"I've got to focus on this event and then Cincinnati. There's so many things I've got to look forward to."

Kyrgios faces countryman Alex de Minaur in the Montreal Masters' round of 16 on Thursday.
