Anderson Silva's Down To Fight Jake Or Logan Paul, 'Everything's Possible'

Anderson Silva is taking his talents to the boxing ring ... and the ex-UFC champ says after his fight with Julio Cesar Chavez Jr. this weekend -- he's totally open to fighting the Paul bros!!

TMZ Sports talked to the 46-year-old MMA G.O.A.T. just days before he fights former middleweight champion, 35-year-old Julio Cesar Chavez Jr. in the squared circle.

FYI, Chavez Jr. -- the son of legendary Mexican fighter, Julio Cesar Chavez Sr. -- has a professional boxing record of 52-5-1 with 1 no contest. He's shared the ring with Canelo Alvarez and Danny Jacobs.

But, if you thought this was a 1-and-done event, you're wrong ... 'cause Spider says he's down to take on all comers -- INCLUDING the Paul bros.

"In the future, everything's possible. The Paul brothers, I respect both. There are good boys," Silva says.

Of course, there are fight game purists who hate the idea of a legit legend like Anderson fighting a YouTuber ... but Silva says things have changed.

"Everything's changing in the world. People like to see the big shows, entertaining shows."
