Real Madrid star Cristiano Ronaldo took his focus away from football matters yesterday to launch his very own underwear range.

The ex-Manchester United player headed to the Palacio de Cibeles to mark the launch of his CR7 range with a 19-metre tall billboard of the Portugal captain in nothing but his underpants.

"I am very proud to officially launch CR7 today and especially to see my campaign image displayed in this beautiful building, one of the most famous landmarks in Madrid," the Daily Mail quotes Ronaldo as saying.

"I put a lot of passion and dedication into creating this new underwear line and I am delighted to finally launch it globally."

Ronaldo is following in the footsteps of former England captain David Beckham, who has his own line with H&M.
