American boxer Floyd Mayweather set a big price for agreeing to return from retirement and confront Irish Conor McGregor or Russian Habib Nur Mammadov in the coming period.

Mayweather, 43, announced his retirement from boxing in 2017 after defeating McGregor and achieving his 50th victory in his unbeaten run.

Since his retirement, the media have not stopped reporting information about the possibility of the American boxer returning in a heavy-caliber confrontation with the mixed martial arts stars McGregor and Nur Mammadov.

Mayweather earlier expressed his willingness to face McGregor and Nur Mammadov in one day, while the Russian wrestler suggested confronting Mayweather in a 12-match fight that mixed martial arts and boxing.

In his most recent statement, the American boxer refused to return to the competition before obtaining $ 600 million, and said, "I am not interested in facing any ordinary competitor ... I am at a stage where I am interested in money ... I am a businessman."

"Why am I facing a regular wrestler for 30 million dollars if I can face a competitor behind an entire country for 300 million dollars?", He added, referring to McGregor's support in Ireland and Nur Mammadov in Russia's Dagestan.

"We talked about a fight with McGregor and Nur Mammadov, and the number for me is 600 million dollars ... If I decide to take risks and go to this fight, the interviewer should be worth it."
