Filipino boxer-turned-politician Manny Pacquiao has warned unbeaten US boxing champion Floyd Mayweather to be wary of his rediscovered 'killer instinct' in the much-anticipated 'fight of the century' bout on Saturday in Las Vegas.
Pacquiao would go head-to-head against Mayweather in the richest fight in history at the MGM Grand Arena in his bid to defeat the undefeated five-weight world champion.
Pacquiao said that he is happy as that feeling of the killer instinct - the focus he had from 10 or 11 years ago- is back, the Mirror reported.
Pacquiao admitted that he hadn't felt like this in his previous couple of fights, insisting that he is 100 percent relaxed and confident of winning the mega-bout.
