NFL star Andrew Luck was spotted at the USA v Belgium game, one fan thinks he’s Michael Phelps [Pictures]

Fans of the NFL were quick to spot an American Football star in Salvador on Tuesday night.

Andrew Luck, the quarterback for the Indianapolis Colts, was spotted on TV screens around the globe as the 24-year-old wore his American national shirt for the match against Belgium.

Several pictures of the NFL star at the USA v Red Devils match have now been posted on social media, however one fan failed to realise who he managed to snare a picture with.

In a comedy Instagram post, one fan thought he was standing next to Michael Phelps instead of the QB for Indianapolis.
