Saul 'Canelo' Alvarez was the epitome of composure in the media presentation ahead of Saturday's huge bout with Billy Joe Saunders, who insisted: "I have come here to win."

In a long-awaited fight that has seen a feisty build-up – including a dispute over the size of the ring and a fiery photoshoot on Wednesday in which tempers threatened to boil over – Canelo and Saunders will meet in Arlington.

Approximately 70,000 spectators, the largest crowd in the United States since the start of the coronavirus pandemic, and the largest ever for an indoor boxing event in the country, will flock to the AT&T Stadium to witness the unification clash.

Mexican Canelo holds the WBA and WBC super-middleweight titles after victories over Callum Smith and Avni Yildirim – the latter fight clearing the way for a meeting with undefeated WBO champion Saunders.

Canelo has won 55 professional fights, 37 by knock-out. There were little signs of any complacency from the 30-year-old, but he coolly declared: "I've been involved in a lot of big fights; this is just another day at the office.

"I come to win; boxing is my life. I come here to win.

"I'm excited for this fight. He's a great fighter, he has a lot of ability and he's also a southpaw, but I'm not the same fighter of six or seven years ago and on Saturday I'll show that."

Saunders, on the other hand, is convinced Canelo is about to meet his match.

"I've been boxing since I was five years old, I've been dragged up. We can all have the rough, tough talks from growing up as kids but I'm here for a reason and there's no other reason for me to be here apart from win. Not about fame, anything else, publicity – win," he said.

"I don't think we've had somebody come to win for a very long time. We've had lots of people fly in, turn up, collect checks and fly out, but we haven't had the heart and soul and the IQ that I will bring to the table and to the ring, to win.

"I can't talk what he's done down, he's done brilliant things for boxing. He's a good champion, but there's a time in life where you get tested.

"Sometimes when you forget where you come from, forget all those hard things that have brought you to where you're at, sometimes that can make it difficult on yourself, and I think he's bumping into the wrong man on Saturday to be walking away with those titles."
