A very eager and motivated Billy Joe Saunders is targeting a middleweight unification fight against the victor of the expected rematch between Gennady Golovkin and Saul 'Canelo' Alvarez.

WBO champion Saunders (25-0) will make his third defence against David Lemieux (38-3) in Canada on Saturday night but has his eyes on the other belts in the division.

Golovkin (37-0-1) retained his IBF, IBO, WBA and WBC straps following a draw in his highly anticipated fight with Canelo (49-1-2) in Las Vegas last month and a rematch has been ordered by the latter governing body.

Saunders believes he should be next in line for Golovkin, or Canelo, should the Mexican come out on top when they go toe to toe again.

"Once I beat Lemieux I'll be moving onto bigger fish - the winner of the rematch between Canelo and Golovkin. I'm looking forward to a great fight," Saunders said

"Lemieux looks good against 'B-level' fighters, but he is now getting in the ring with someone who is far more superior and slick than anyone he has ever been in with."

Lemieux has recorded four straight wins since being stopped in the eighth round by Golovkin two years ago.

In his last fight, Lemieux (38-3, 33 KOs) outpointed Marcos Reyes at Las Vegas's T-Mobile Arena in May.

Lemieux is so confident of a victory that he boasted it would take a low blow from a baseball bat for him to lose to Saunders.

He believes his power will indeed be the key to victory in the contest and he expects to batter Saunders in every round.

"I don't know how he can say that he will knock me out. He's going to hit me in the crotch with a baseball bat? There's no way Saunders is going to drop me. But if he somehow makes it to the end of the fight, I promise he'll be in the hospital," Lemiuex said.
