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.
