Last week, the sportsman met One Direction at the Spanish club’s training ground, as the boys took some time out from their whistle-stop European tour to train with Jose Mourinho’s men in the Spanish capital.

At the end of their brief kickabout, three of the band members enjoyed a meet-and-greet with the manager, who presented them with a Real Madrid shirt, before they caught up with the players.

“They told us that we had the opportunity to come to see the Real Madrid players and that was very exciting for us,” revealed Niall Horan.

“It is amazing to see how they train and see so many such good players. We are big football fans and Real Madrid are one of the best teams on the planet.”

Fellow bandmate Liam Payne added: “Cristiano Ronaldo is my favorite player, he is one of the best in the world.”
