Young Valencia CF fan 'Super Leo' suffers from Pontine tegmental cap dysplasia (PTCD), a rare disease with only 30 diagnosed cases worldwide, and just 2 in Spain. A non-progressive neurological disorder characterised by significant developmental delay, cranial nerve dysfunction, and malformation of the hindbrain, currently little is known about the condition.

Despite living in Caldas de Montbui in Barcelona, Leo has supported the club from birth, thanks to his parents and grandparents and their Valencian roots. 

He has made several visits to Mestalla, the latest of which saw him catch up with Valencia CF player Hugo Guillamón.
