The world has been waiting for a Floyd Mayweather/Manny Pacquiao showdown for a few years now. I still think it won't happen until I see both of them touching gloves in the ring. This is the fight boxing needs to gain interest that it's lost over the past decade. There are a number of reasons, but the main reason is the best fighters never fight each other.
Once again Floyd Mayweather has issued a challenge to Manny Pacquiao through Twitter. How else would he do it in today's day and age. It might be for show to see if Pacquiao will take the challenge.
