Suarez moved to Villarreal from Barcelona in the off-season and the Spanish champions have confirmed that there is a possibility that they could re-sign their former player.
The 21-year-old has been a key figure for Villarreal this season, scoring three goals and providing five assists in 13 league appearances, and Roig is adamant that he will remain their player until at least the end of the season.
"There is an option for the summer, at the end of the season, but not until then," he explained to the press.

Roig says that a move for the 25-year-old could be in the offing, either in January or at the end of the season.
"[Cheryshev] is also liked by our coach and, if we could get him, he would be a great help," he remarked. "We may try to sign him and we will soon see what happens.
"If there's someone who could help a lot, we will do it, but we think that, in general, we have a great squad."
