Former four division champion Juan Manuel Marquez (56-7-1, 40KOs), 41-years-old, is still undecided on his future. But if he decides to return next year, he will only take part in a single fight and then plans to retire from sport - although he leaves the door open for a second fight.

Marquez would like to go for a welterweight world title. IBF champion Kell Brook has been mentioned by Marquez and his trainer Nacho Beristain, and Brook's promoter Eddie Hearn of Matchroom Sport is very interested in making that fight. Brook has a tentative return date at the end of March.

"If I return to the ring I would just make a [single] fight and then I'll retire, that's what's feasible and what I want to do, although it may be that I feel good and say I'll do one fight and I do two, but what I think is a [single] fight and then I'll hang up the gloves," Marquez said.

"I have to make the best decision based on how I feel physically. Then I have to see what fighter will be chosen. Maybe a fight against Kell Brook might be the [the final one] or maybe I'll do a retirement fight here in Mexico."

"In January I'll make one of the most important decisions of my life. Right now I'm going to start training and in December I will increase the intensity of my training to see how my body responds and by mid-January I'll know if I'm going to have a retirement fight or just return to the ring."
