His outlandish dance routines, out of tune singing and failure to remember the words to his songs have left some questioning Wagner's continued presence on the X Factor.
But it seems the apparent underdog is actually one of the favourites, with bookmaker William Hill recently cutting his odds to win from 100/1 to 14/1.
According to reports, the 53-year-old is in the top half of the X Factor vote every week.
A Facebook group urging the public to vote for the Brazilian former PE teacher has more than 30,000 members.
One wrote: "I had never voted in any of these talent contests before but Wagner has become an anti-hero. He is everything the show doesn’t want. And that makes it funny."
