The middleweights are set to battle in out on the Gennady Golovkin v Canelo Alvarez rematch card at the T-Mobile Arena, with the winner slated to challenge the winner for all the middleweight marbles.
According to several bookmakers offering Free Bets in Canada, Lemieux is the favourite to prevail, and the former IBF title holder is sure a return to form is on the cards.
“It’s been a long time I’ve been waiting for a big fight like this. I’m extremely ready and I’m extremely excited. I expect — that I haven’t seen in a while. I’m very prepared for this fight. It’s been a long time I’ve had a preparation like this. It’s going to be devastating,” said Lemieux.
“This fight is about getting back on top, so I’m preparing myself for that. I’ve been waiting for an opportunity like this for a while now to get back on top and I’m very confident that I’m going to not just beat O’Sullivan but look amazing against him.
“I’m extremely confident and I can’t wait for fight night. Give the fans what they want to see.”
In his last big fight, Lemieux was tamed by Billy Joe Saunders in December 2017, a fight which went viral for the manner of the defeat handed down to the French-Canadian by the Brit.
Facing months of flak from Saunders’ fans, Lemieux is finally ready to take out his frustrations on the biggest stage and has warned O’Sullivan of the devastation to come for the Irishman.
“(Billy Joe Saunders) didn’t fight Lemieux in top shape. I’m going to be in top shape against Spike. So, Saunders, I wasn’t at my top, but I will be against Sullivan.
“I’ve been working against a lot of injuries that has not been fixed and it’s been put in the past. I’m in tremendous shape and feeling great. I can use both my hands. I can use everything. I can use all my tools.
“So I think Lemieux is back and about to demonstrate what I can do against O’Sullivan on the 15th. I think a lot of people are going to be surprised what I bring to the table, and it’s going to be an exciting fight. I’m not the guy I was against Saunders.
“This fight is definitely going to go my way. You guys watch and see, and I’m going to make spike eat all his words. To say any excuses against Billy Joe or whatever — I’m not giving uses. I’m giving facts.
“But now let’s see what happens on September 15. The fight is done and let’s just walk the walks and see what’s up,” he added.
