Novak Djokovic has not lost any motivation for tennis, but believes he needs time to find some rhythm after a long break, as he conceded the world number one spot.
Djokovic's 86-week reign at the top of the ATP rankings will end on Monday, after the Serbian lost to qualifier Jiri Vesely 6-4 7-6 (7-4) in the Dubai Tennis Championships.
That means that Daniil Medvedev will leapfrog Djokovic regardless of whether or not he wins in Acapulco.
Using his official Twitter account, Djokovic congratulated both Vesely – who won his only previous meeting with the 20-time grand slam champion back in 2016 – and Medvedev.
"Well played @jiri_vesely, that was a great game. Wish you the best of luck for the rest of the tournament," Djokovic wrote, accompanying his post with a thumbs up emoji.
"Congratulations also to a very deserving @DaniilMedwed, who will now become world number one."
His appearance in Dubai was Djokovic's first competitive action of 2022, after he was unable to feature at the Australian Open due to his refusal to be vaccinated against COVID-19.
While suggesting he is still working his way back to full sharpness after not playing since December, Djokovic insisted he is fully motivated to carry on playing.
"My goal is to keep on playing tennis," Djokovic said in his post-match news conference.
"That's the ultimate goal. For as long as I really feel like it and as long as I can play. As long as my body allows me, as long as the circumstances in my life as well, the people that surround me [and] support me.
"I'm still motivated and I'm still p***** off when I lose a match. I care about it. I care about winning every match, as anybody else on the Tour, regardless of the age. I'm actually glad that I'm feeling a lot of emotions every single day because it means that I really want to be part of this sport, part of the Tour.
"Unfortunately, [it] wasn't my day. I congratulate Jiri. He played better.
"The more matches I play, the more comfortable I get on the court. I need the match play. I didn't have many matches at all last few months.
"I don't look at the age really as a restricting factor for my career. I still feel great in terms of my body and the way it's holding on, the way it's recovering. It's been serving me well, so to say. That's something that obviously encourages me to keep going."
