McGregor faces off with Ronaldo

Millions admire him. Millions love to hate him.

Are we talking about Conor McGregor or Cristiano Ronaldo?

The Portuguese football deity visited the UFC featherweight champion's Straight Blast Gym in Dublin, Ireland Sunday, and he posed for pictures with McGregor and SBG head coach John Kavanagh.

You can't help but think that playing MMA fighter for a day was just the latest excuse for Ronaldo to take his shirt off.
