Amir Khan admits old sparring partner Manny Pacquiao's nasty knockout last weekend gave him plenty of food for thought as he prepares to meet Carlos Molina on Saturday.
The Briton takes on undefeated local lad Molina in Los Angeles desperate to put on a performance after defeats in his last two fights.
His American counterpart is a huge underdog for the fight and only has seven stoppages among his 17 wins. But Khan is wary of underestimating him, especially after his old friend Pacquiao was rendered unconscious by Juan Manuel Marquez on Saturday.
That sixth-round knockout not only proved that nothing can be taken for granted in the ring, it also vindicated Khan's insistence that anyone can be caught with a devastating punch following his stoppage by Danny Garcia in July.
"(Molina) is seen as the massive underdog but I never treat anyone as an underdog going into a fight," said Khan.
"Look at Manny Pacquiao against Juan Manuel Marquez and Andre Berto against Robert Guerrero. I tipped the guys who lost.
"This is why boxing is the best sport in the world - and the toughest sport in the world - because you just don't know what your opponent is going to bring to the table.
"I got caught with a shot against Garcia.
"Look at how Manny Pacquiao got caught the other day by a guy he should have beaten. That's the sport we're in, where one punch can change a fight."
Khan (26-3, 18KOs) added: "Molina is a tough guy, he comes forward, he's confident because he's never tasted defeat before.
"People can say all sorts, such as he's never fought anyone as good as me, but he's had a lot fewer fights like me and he's stepping up to world class so he's going to be training twice as hard and putting himself through the pain barrier.
"Having brothers who have been champions and won world titles is only going to give him that extra push. We know he's dangerous, we know he's going to come at us.
"Having the fight in LA, his backyard, always motivates a fighter that little bit more too. It's only going to lift him. Look what it did to Lamont Peterson when I fought him in Washington last year.
"I'm sure it will motivate Molina the same way.
"I think by coming to his town to fight him shows what sort of character I am, too, by fighting someone again in their backyard. But that's the way I like it.
"We know he's going to be ready and that's what makes this fight more exciting, the fact he's undefeated and I'm coming off a loss. People want to see if Amir Khan's still got it in him.
"It's not a no-win fight for me - it's a big-win fight for me. Because if I get through this one then the confidence comes back. The fight is a chance to put all that work that I've been doing in the gym with Virgil into practice in an actual fight. Yes, you can say I've been able to do it in sparring, but it's not the same as actually fighting."
Molina (17-0-1, 7KOs) is revelling in his role as the outsider.
"I know a lot of people see me as the underdog, but man, little do they know that we're going to shock everybody," he said.
"We're going to be called the Seabiscuit after this fight. We're going to come out of nowhere and shock the world."
