Granada have almost certainly assured their survival in La Liga after a 2-1 win over Espanyol on Tuesday evening, moving eight points clear of the drop zone.
Ighalo scored twice in the first half before Didac pulled one back after the break.
Villarreal needed to win to give them a chance of survival and they duly obliged, beating Sporting Gijón 2-3 in a match which saw red cards late in the game for the Sporting coach Javier Clemente and Villarreal reserve goalkeeper César.
Mario, Marcos Senna (penalty) and Hernán Pérez were on target for Villarreal, Lora and Gálvez scoring for the home side who are now almost certain to be relegated.
