It’s a privilege and it’s pressure. “This is my chance to write a chapter that belongs to me, and it’s the legacy defining moment of my career.”“Lara is an great champion. He’s slick, he’s clever and stylistically he’s very hard. “He’ll want to turn this into a chess match but I’ve never taken the easy road. I want the man with the belt, and I’ll drag him into a fight he doesn’t want.”Lara is on a seven-fight winning streak as champion, and is hoping to continue his form at 43GETTY“At 160 I feel strong, I feel sharp and I feel dangerous. Middleweight is my division now. Spence was just the appetiser.”“Having Jeff Fenech in my corner means everything.
