Jose Canseco Says Logan Paul Beef Stems from Bad Break Up with Daughter Josie

Jose Canseco is REALLY pissed at Logan Paul over the breakup with his daughter — suggesting something scandalous went down behind-the-scenes.

The ex-MLB star isn’t spilling all of the tea … but says the split between Logan and supermodel Josie Canseco earlier this year “left me with a bit of a bad taste in my mouth.”

Now, 56-year-old Jose wants to FIGHT the 25-year-old YouTube star to defend his family’s honor.

… and yeah, Jose insists this is for real.

“I actually met him when my daughter and Logan came down to Vegas,” Jose said this week to Sports Talk Chicago on AM 1530 WCKG.

“He seemed like a very nice young kid — to me, seemed a bit on the arrogant side. But, then all of the sudden they broke up.”

“I gotta give you the final details, they will come up .. but you know, it left me with a little bit of a bad taste in my mouth.”

Once Jose floated the idea of boxing Logan on social media back in November, Logan replied, “No problem. I love smashing Cansecos.”

Yeesh.

Now, Jose is calling for LP to back up his words … saying he’ll be waiting for him after his exhibition with Floyd Mayweather next month.

“Get ready, this is real. This is not a joke … If I hit him, he’s going down.”

Jose also says he’s not intimidated by Logan’s age and boxing experience — saying, “Even though I’m 56-years-old, I do have some martial arts and celebrity fighting experience.”

Jose even references his 2009 fight against South Korean MMA star Hong-man Choi — a 7’2″ monster who beat down Jose in just over a minute when they squared off.

“After fighting a guy who’s 7’2″ and 400 pounds, these guys look like shrimps to me,” Jose says.

As for his strategy, Jose says he will channel his inner Rocky Balboa … using 3 words to finish Paul off — “Blunt force trauma.”
