There’s not always an exact reason things go together so well. Sometimes, they just jell. 

Danny Garcia. Barclays Center. 

They just jelled. 

The 34-year-old Philadelphia native returns to Brooklyn and Barclays Center as the main event Saturday night (9 p.m., Showtime) against Jose Benavidez Jr. The fight will be Garcia’s ninth at the venue, in front of a fanbase that’s grown to adore him as one of its own. 

“It just went together, like one and two,” Garcia told The Post. “They know when I come to Brooklyn, I give them a good fight. And the word just goes around. Ten years of fighting, giving people great fights, and legendary fights … and there’s a lot of Hispanic, Puerto Rican people up there, a lot of hip-hop fans, so it’s just like the diversity. Everybody loves me — Polish people, Russian people. It’s crazy, I can’t explain it. 

“I definitely feel it in the atmosphere. It feels like a special night. Every time I walk out of that tunnel and I look at the crowd, it just feels like a special night. Like a legendary night.”  

Garcia, 36-3, certainly had his fair share of “legendary” bouts in Brooklyn, including title fights against Zab Judah, Erik Morales, Keith Thurman and Shawn Porter. This time, however, he returns with new priorities. 

A two-division world champion at super lightweight (140 pounds) and welterweight (147 pounds), Garcia is now moving up for his debut at super welterweight (154 pounds) as he chases a belt in a third weight class. 

Coming off the longest layoff of his career (19 months), Garcia, who never gets bigger than 175 pounds between bouts, feels like 154 pounds is his most natural weight. In his return to the ring, he was obsessed with not “taking a step back” in his career, and he promises a new weight class and starting the path to a new world title, is the best way forward. 

“It’s just a dream of mine. A dream of mine,” Garcia said. “I always said, from the very beginning of my career, I want to be a three-division world champion. And I want to fight in three divisions. And now this is the perfect time for me. I fought everybody at 140, I fought everybody at 147, and now I’m going to go up to 154 and put the icing on the cake.

“They’re naturally bigger than me, they’ve been at that weight class a lot longer. But I feel like I’m gonna be the fresher guy. Coming up, they’ve got to kill themselves to make weight, I got a lot of experience, I’ve been in a lot of great fights, so I just got to go in there and use my advantages against those guys.”

Beyond representing a dream, the new division also represents a reset. 

At 33-0 and holding the WBC welterweight title, Garcia began his quest to take on other champions in the division and unify his belt. He lost to WBA title holder Thurman, relinquishing his own belt in the process. Two fights later, the Porter bout gave him a shot to regain his WBC title, but he lost in a unanimous decision. Three fights later, he fought Errol Spence Jr. for the WBC and IBF belts, but again lost by unanimous decision.

Garcia had challenged the elite at welterweight in an effort to climb atop the pound-for-pound rankings. Instead, it cost him three losses in a six-fight span, halting much of the rapid momentum toward the Hall of Fame and an all-time legacy he was making. 

Now, he’s got a new division — and fresh chapters to his legacy — to start adding back. 

“You learn, you learn. You learn. You learn from your wins and your losses,” Garcia said. I felt like I won the Porter and the Thurman fights, I always feel like that. Even when I watch those fights, over and over, I still feel like I won those fights. So that hurts me a little bit, knowing I didn’t get the decisions, but you learn from everything. You learn from every fight, I really can’t cry over spilled milk, just gotta go in there and rebuild, look good.” 

And where better to do it than in his favorite arena? 

Coming off a loss — the Spence fight — Garcia knows how much pressure there is on him to beat the dangerous Benavidez (27-1-1) at Barclays Center and re-establish his stature. And not just to win, but to prove he can still be a fighter deserving of title chances. Coming off a long pause, and with the wisdom gained through the first roadblocks of his career, Garcia has perhaps never been better-equipped to do just that. 

“I actually feel like I’m a better fighter now than when I was young,” Garcia said. “But when I was young, I just took more risks, and that’s just what people loved about me. I could probably criticize myself, I didn’t take as many risks as I did before, I felt like I was trying to be a smarter fighter, better fighter, maybe that cost me, that I didn’t go for the extra risk, but I feel like I still have that in me. I still have that risk-taking attitude in me. I want to show it to people. That will be the difference in the rest of my big fights, I’ll just have to take risks. Maybe that one round that I take the risk will be the round that makes me win the fight.”
