Villarreal had two replacements lined up for Unai Emery this week.
Emery was the priority target for managerless Newcastle United, only for an announcement via Villarreal's media channels that he would be staying.
Sport says while expecting Emery to stay, Villarreal did draw up a contingency plan.
The Yellow Submarine were in contact with former Barcelona coach Ernesto Valverde about stepping in should Emery depart.
Former Granada coach Diego Martinez was also being discussed at Villarreal.
