The 25-year-old defender had joined Gimnastic from Cordoba, but the deal lasted only four hours as the Primera Federacion club swiftly annulled it after severe backlash from fans. Notably, Calderon had made some anti-Catalan statements after securing promotion with Cordoba to the Second Division. The incident occurred last year after the qualifying round of play-off between the Andalusian team and Barca Atletic.
"I sh*t on all dead Catalans," the left-back said in a live broadcast on his Instagram account. He later apologised, saying: "I apologise to all the people of Barcelona and all Catalans for my actions during this afternoon's live stream."
Barca midfielder Casado, who clashed with Calderon during that playoff tie, publicly welcomed Nastic's decision, which earned him more praise from La Liga fans.
