Ronaldinho
Although he retired in 2018, the Brazilian midfielder has continued to build a huge social following. His 70 million followers across Twitter and Instagram, plus another 34 million-plus on Facebook, makes him a desirable pitchman for companies looking to make an impact—both in humanitarian and financial efforts. Like some of the other internationally successful footballers, Ronaldinho reportedly commands six figures (somewhere in the $250,000 range) for posts.
