In the match at the BNP Paribas Open just ended yesterday, Medvedev won the first set with just one serve. At the 9th game, Medvedev leads 5-4 and the UK ends set 1 with the advantage of leading 6-4.
In the second set, Medvedev was unable to find a good feeling, although Monfils also did not really good when continuously communicating the serve. Medvedev failed and lost 3-4 after 7 sets.

Since then, Medvedev has easily lost opponents in the following games. Monfils ended the match with a score of 2-1 and he also prepared to end the short time in the world's No. 1 position of the opponent.
Because after this defeat, Medvedev will definitely be reclaimed by Novak Djokovic as the world's No. 1 position even though the Serbian player does not play. Medvedev is only 150 points higher than Djokoivic before attending the BNP Paribas Open, while at the upcoming chart announcement, he will be deducted 250 points from the Marseille Open last year.
Thus, with the early elimination at BNP Paribas Open, Medvedev did not have enough points needed to stay on the top. He only sat on the top of the world for 3 weeks before having to return it to the familiar owner, Djokovic.

Talking about this defeat, Medvedev admitted that he came to the United States to play without the best form. But the Russian player insisted that he did not fail because he felt the pressure to hold the top. “I simply don't play well,” Medvedev said. “Sometimes you feel unwell in the tournament. So I will come back and try to play better before.”
