Robert Guerrero has used Twitter to taunt Floyd Mayweather ahead of their May 4 clash.

Mayweather was working in the corner of J'Leon Love for his fight with Derrick Findley on Saturday, which led to Guerrero using the social networking site to try and start a war of words with the unbeaten fighter.

"Hope you liked working corners I'm gonna make it permanent pretty boy!" Guerrero tweeted.

"70 days left buddy #43-1"

The fight will take place at the MGM Grand in Las Vegas.
