Marbella's first game back at the Antonio Lorenzo stadium produced the biggest victory at this level in their history - a 5-1 win over Marino on Sunday.
The visitors made it more difficult than the scoreline would suggest. In fact, the first half ended level with a goal apiece. Tresaco gave the around 800 fans present their first goal to cheer after 17 minutes when he was sent through on goal before tucking past keeper David.
The side from Sabiñánigo were back in the game just six minutes later when Ahmed converted from the penalty spot after a bizarre foul from Busquets.
The second half was a completely different story. Despite being caught out playing a high line once after the break, Marbella persisted and dominated the game as a result.
In the 63rd minute, Edu Ramos scored the goal of the match day from 27 metres, and from then on the hosts smelled blood.
Granero, who had his best game since joining Marbella from Espanyol, then set up Callejón to open his account for his new team.
Centre-back Blanco then banished any memory of defensive uncertainty previously by heading home the fourth from a corner.
The icing on the cake came when substitute Añón teed up Manel for the history-rewriting fifth goal.
