Does the world's youngest All Blacks superfan live in Spain? Maybe.

Little Alex Moras Fuster calls Madrid home. He should be obsessed with football. But it's not Fernando Torres or Cesc Fabregas the 20-month-old demands to watch on the computer every day.

It's Tana Umaga, the All Blacks and the haka.

Alex's parents, Francisco Moras and Carmen Fuster, sent the NZ Herald a video of their rugby-mad son. Dressed in a miniature All Black kit, little Alex catches a rugby ball almost as big as him, runs down the hallway to score a try and even - in true men in black fashion - picks himself up after a nasty knock to the gob.

Alex from Spain is an ardent All Blacks fan at just 18 months of age

Mr Moras said he played rugby himself as a child and loved the All Blacks. He had passed that passion on to his son, playing him videos of the haka when he was a baby and planning to enrol him in a rugby club when he is older.

"I think that [it] is a beautiful story, because in Europe the most popular sport is soccer."

Ms Fuster said Alex especially enjoyed watching the haka.

"He always says 'more, more'. And my husband bought his All Black t-shirt and trousers online, which [Alex] loves very much."

The couple plan to take Alex to New Zealand when he is five or six years old, and attending an All Blacks match will definitely be on the itinerary, she said.
