Timothy Bradley said Tuesday that Juan Manuel Marquez will be “the strongest challenge of (his) professional career.”

Bradley (30-0-0-1, 12 KOs) is slated to defend the WBO welterweight belt against the 40-year-old Marquez (55-6-1, 40 KOs) on October 12 at the Thomas & Mack Center.

Marquez last exited the squared circle in December after brutally knocking Manny Pacquiao onto Queer Street.

Conversely, “Desert Storm” most recently vacated the ring on March 16 with a narrow unanimous decision win over Ruslan Provodnikov.

“Without doubt, Marquez is the best boxer I have faced in my career,” said Bradley, 30, who was controversially declared a split decision victor over the 34-year-old Pacquiao (54-5-2, 38 KOs) in June 2012.

“He fought the best fighters in the world and has had big fights. It is without doubt the strongest challenge of my professional career. I want to beat him so people realize the kind of fighter I am and know that a win will put me at the level of the greats of boxing.”

Marquez is a badass Mexican and relentless bruiser.

To offset Marquez’s ruggedness, Bradley must utilize his blazing hand speed and elite footwork.

Provided the champion isn’t lured into a slugfest, Bradley can outscore Juan Manuel Marquez to remain an undefeated titlist.

In an extremely intriguing and seesaw bout, Timothy Bradley will trump one “of the greats of boxing” on the cards.
