Carlos Molina has issued a warning to Amir Khan ahead of the bout between the duo in California this weekend.
The undefeated lightweight scrapper is unconcerned by his opponent's new tactical focus, insisting that the Bolton fighter will crumble under pressure on the night.
"Like the great Mike Tyson says, everyone has a gameplan until they get smashed in the face," The Sun quotes Molina as saying.
"And that is going to be the story here. Khan is going to come out and be defensive in the first part of the round but once I put on the pressure and start landing my punches, he is going to go back to the same mould.
"It will be the same old Amir Khan as we have seen in his last few fights. He will get wild and that's only going to benefit me when he starts opening up. He is going to feel my power."
Khan previously admitted that this Saturday's showdown with Molina is a "make or break" fight.
