Cape Town - Daniil Medvedev has warned Rafael Nadal and Novak Djokovic that he feels 'invincible' right now and believes he can become world No 1.
The Russian beat Alexander Zverev in the Shanghai Masters final on Sunday - his second successive Masters-level crown - to surpass Roger Federer in the race-to-London rankings.
Speaking afterwards, Medvedev stated that he is not ready to stop there as he attempts to re-order tennis' established elite.
"I always say that my first goal is to win every match I play, and that's how I can actually become number one if you win a lot of matches in a row just like I did," Medvedev explained.
"I'm going to try my best to show great results as I did here, and if something like this is going to happen, it's just a big bonus.
"I don't like to talk about the future, because you never know what the future got for you. That's why my answer stays the same.
"This week (in Shanghai), yes, I probably was invincible, but for the next upcoming weeks, I'm not sure."
Rafael Nadal will become world No 1 in November, and beat Medvedev in a stunning US Open final last month.
