Spanish pair Mario Gaspar and Manu Trigueros have both signed new long-term deals with Villarreal.
Gaspar, who is a product of the club's academy, would have been out of contract next season under his previous agreement, but has now put pen to paper with the Yellow Submarine until 2019.
Trigueros, meanwhile, who joined on a free transfer in 2012, has also signed a two-year contract extension until the summer of 2019.
Both players have been key members of Marcelino's first XI this season.
