Khabib Nurmagomedov will try to persuade Cristiano Ronaldo to stay at Manchester United.
Ronaldo signed a two-year deal with the Manchester club last August but has struggled to find his best form in recent weeks.
The Portuguese forward is currently in his second stint at United, having scored 118 goals when he spent six years at the club before his 2009 departure.
Despite being 37-years-old, Ronaldo is the joint-sixth top scorer in this year's Premier League campaign and Nurmagomedov thinks he greatly benefits his side.
"He became 37 years old, this is not his best age but even how he plays, I think affect his whole team. His energy, his experience, his advice," Nurmagomedov told Sky Sports.
"They have a very good, strong, young team. Next year I feel they will do a very good job, right now so many new players they don't connect well.
"I think next year Manchester United are going to be big problem for all clubs. I'm going to talk with him."
Now-retired UFC star Nurmagomedov said he thought a friend was joking when they told him Ronaldo followed him on social media in 2018.
The pair have since voiced their support for each other, with Ronaldo backing his "brother" Nurmagomedov before his final UFC fight against Justin Gaethje in 2020.
Nurmagomedov is a big football fan and an avid supporter of Ronaldo's former club Real Madrid.
The former UFC lightweight champion reportedly signed a deal with Russian football club Legion Dynamo last year, but he later denied the claims by stating he only has "close relations" with the side.
And Nurmagomedov said Ronaldo has often kept him up to date with his career moves in the past.
He said: "I remember when he moved from Real Madrid [to Juventus ] he told me a couple of months before he moved and when he moved from Juventus [to Man United] he told me.

"But I don't go to media, I am not like a journalist. I'm gonna ask him, honestly I want him to stay [at Man United].
Nurmagomedov has admitted he would accept a contract to play football if the right team offered him one, adding that he loved the sport long before his MMA career.
"If some clubs, they offer me a [contract] and make me (interested), I’m gonna accept this. Because this is my childhood dream. I love football. I follow football since when I was kid, when I was child," he said in a Facebook Q&A.
"This is my first love. Football is on another level. MMA, I like MMA. I like fighting, I like competition with people, with best fighters in the world. But football, for me, is [the] best sport."
