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 tomorrow.

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,’’ Khan said.

‘‘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.’’
