The 37 year-old ended his brief retirement over the summer before the pair collided for Golovkin’s 160 pound belts on September 10 in London, with Brook coming out on the wrong end of a fifth round stoppage.
Upon witnessing the fight, Pacquiao believes any doubts in his mind about fighting Jessie Vargas where firmly pushed out as the Filipino Congressman focuses on regaining a world title of his own this weekend.
“I happened to see Triple G fighting Brook and suddenly I feel lonely, sad,” Pacquiao said according to The Daily Mail. “I am thinking I know what Brook should be doing to have a chance. Countering instead of taking on a big hitter.
“I find myself thinking that I’m no longer doing the sport I love. I know I still have the speed, the power and the hunger and I am asking myself: ‘why didn’t I continue?’
“I don’t normally watch other fights. But for some reason I did this time. I am thinking I know what Brook should be doing to have a chance. Countering instead of taking on a big hitter.
“Golovkin is bigger, stronger. He is not only a powerful puncher but he is heavy handed. There is a difference. A heavy-handed opponent can hurt even if he doesn’t land clean. However, they hit you, it makes you think.
“I’m fighting this fight in my mind. And I’m hooked, again. In that moment, my decision to come back is made (correct).
Brook, like Vargas, was a big underdog heading into the fight and Pacquiao will be hoping for a similar ending to give him his first early night since way back in 2009 against Miguel Cotto.
