Former UFC middleweight champion Anderson Silva feels the company has shown him a lack of respect, according to recent statements he made to a Brazilian news outlet.Speaking to UOL, Silva said the UFC never showed him appreciation for accepting a short-notice fight against Daniel Cormier at UFC 200 on July 9 in Las Vegas.Silva (33-8) took the fight on two days notice, less than two months after he underwent surgery to remove his gall bladder. The UFC needed Silva to replace Jon Jones, who was pulled for a failed drug test.Man, its complicated to talk about it, said Silva, as translated by MMAFighting.com. I didnt even get a thank you from [UFC president Dana White or former CEO Lorenzo Fertitta] after my last fight.I was the one who wanted to fight, of course, I took the fight, but I know what Im worth, my importance. I was really disappointed with the lack of respect from the UFC towards Brazilian athletes. Im an athlete who took the sport to another level. I dont get or ever got the respect from people. That made me really upset, sad and disappointed with the UFC.Silvas comments come on the heels of a similar sentiments made by interim featherweight champion Jose Aldo. The most dominant 145-pound champion in UFC history, Aldo, 29, requested his release from the UFC late last month. Fighting out of Rio de Janeiro, Aldo also stated he felt a lack of respect from the UFC.Silva has expressed interest in a rematch against current middleweight champion Michael Bisping, who defeated him via unanimous decision in February. Silva told UOL the UFC offered to essentially have him on standby as a replacement for last weekends fight between Bisping and Dan Henderson. Bisping defeated Henderson via decision.I didnt talk to them or anyone after my last fight, Silva said. They even offered me to stay in standby in case something happened with Bisping or Henderson. But its more absurd how that [offer] came. They didnt even talk to me. My representatives came as a messenger pigeon. Im not the type of guy to get messages. After everything Ive done, I still have to stand by and wait for a fight I won? I found it a little unpleasant.I will say it again: Im really disappointed with the way they have treated me, very upset with all that. I was not the one who said I was the best pound-for-pound fighter in the world. Dana said that. Maybe he said that to promote the event or because he really thought that.
