The forward scored the third goal in a 3-0 win over the struggling Primera Division side and was impressive throughout the Copa del Rey semi-final second leg, which crowned an 8-0 aggregate win.
"Afellay offers Barcelona many new options and we will provide him the opportunity to play. He is very dangerous when he breaks into the opponents' penalty area and generally has a great impact on the game. He will do well if he continues to evolve," Zubizarreta was quoted as saying by Sport.es.
Afellay has been considered one of the bargains of the January transfer window, as the Catalans signed the 24-year-old for just €3 million from Dutch giants PSV.
