The match that would serve as the final straw in the systematic campaign against Mateo was a crucial reserve team fixture against Real Madrid Castilla in April 2013.
The game carried enormous significance for both teams, with promotion to the Segunda División hanging in the balance and scouts from across Europe in attendance to observe the continent's most promising young talents.
The morning of the match dawned crisp and clear in Barcelona, the Mediterranean sun casting long shadows across the Ciutat Esportiva Joan Gamper as players arrived for their final preparations.
The atmosphere was electric with anticipation, but beneath the surface excitement lay an undercurrent of tension that would soon explode into the most public demonstration of institutional betrayal that anyone could have imagined.
