Former WBA and IBF light-welterweight world champion Khan bounced back from consecutive defeats to Garcia and Lamont Peterson with a convincing defeat of Molina in Los Angeles.
Khan was stopped in the fourth and floored three times when he faced Garcia in July, but is adamant he can exact revenge with the help of new trainer Virgil Hunter.
“I’d love the rematch against Garcia because I know deep down I’m a better fighter than him,” said the 26-year-old. “I’ll knock Danny Garcia out. We want the rematch – any time, anywhere – but I don’t think Garcia will.”
A rematch with Peterson is his other likely next fight, although Garcia, who is set to defend his WBC and WBA titles against Zab Judah in February, insisted he would be keen on a rematch.
Garcia said: “If the money’s right then we’ll definitely fight whenever and wherever.”
