Villarreal goalkeeper Pepe Reina feels they're now adjusting to the methods of coach Quique Setien.
Setien stepped in before Christmas after Unai Emery's departure for Aston Villa.
Reina explained, "They are two different philosophies.
"We had the break for the World Cup to work and assimilate Quique's ideas. We have had to change and that required a period of adjustment."
Villarreal currently sit in seventh place on the LaLiga table.
