Yesterday, Cristiano Ronaldo added to his legendary resume by scoring two goals to help Real Madrid beat Juventus in the Champions League final. The victory gave Ronaldo his fourth Champions League title, during which he finished atop the scorers' table for the fifth year in a row.

Excited to see one of its own dominate the beautiful game, Nike released a subtle, but strong Ronaldo ad following the final. The ad features an image of a younger Cristiano, with the text "This Boy Knew" and a Swoosh near the bottom. The soccer star also shared the visual on his personal social media accounts.

However, Twitter detectives quickly pointed out something interesting about the photo—Ronaldo was wearing an Adidas sweatshirt in the original version.

Adidas, whose premier soccer athlete is Lionel Messi, has a kit deal with Real Madrid and is rumored to be on the verge of signing a mega-extension with the club. Ronaldo signed his first deal with Nike in 2003, when he joined Manchester United. Last year, he inked a lifetime pact with the brand worth a reported $1 billion.
