Daniil Medvedev is set to lose the No. 1 spot at the ATP Rankings on Monday to Novak Djokovic.
The Russian admits it will serve him as a motivation ahead of the Miami Masters as he attempts to reclaim the top spot.
He only managed to retain the World No. 1 spot for less than a month after replacing Djokovic on February 28.
The 26-year-old suffered a surprise Indian Wells third round defeat to Gael Monfils.
Djokovic who is not competing in Indian Wells will replace the Russian at the No. 1 spot next week.
Medvedev said, per Mario Boccardi: "Now I know I'm going to lose it, so I have Miami to try to get the top spot back. Usually feeling a little bit better in Miami, so we'll try to play good there.
"You know, I always say, when I play my best tennis, it's really tough to beat me."
