Michael Bisping is currently gearing up to fight Anderson Silva in the main event of UFC Fight Night London on February 27th.

Ahead of the fight, Bisping started the trash talk on Twitter, telling Silva to leave the viagra out of his prep for this fight, an obvious insult at Silva’s failed drug test after his UFC 183 fight with Nick Diaz.

Earlier today on the UFC Fight Night London media conference call, Bisping spoke about Silva’s failed drug test saying:

“It blows my mind. Anderson said something about trash talk because I made a reference to Viagra on social media. To be quite frank, I’m blown away by his arrogance,” Bisping said. “How on earth do you expect me not to mention that in your last fight you tested positive for three banned substances? You expect me to not mention that? That’s very, very relevant. So of course I want him to be tested. The fact that he wants me to not mention that, to brush it under the carpet, I’m blown away by his arrogance.”
