In a homecoming match in Brazil in January, Charles Oliveira wants to take on the recently-returned Conor McGregor.
The former lightweight UFC champion will compete against Islam Makhachev, a student of Khabib Nurmagomedov.
However, Oliveira will only take on the No. 4 contender if the UFC pays him "a lot of money."
In the opening round of his trilogy match against Dustin Poirier in July 2021, McGregor, 33, damaged his leg.
Oliveira, 32, defeated 33-year-old Justin Gaethje in the first round of their fight in May.
But the day before, he had his UFC title removed from him because he had weighed in 0.5 pounds too much.
