Denis Suarez says he's happy at Villarreal but he could return to Barcelona this summer.

Suarez who spent the 2014-15 season on loan at Sevilla from Barcelona, signed a four-year contract with Villarreal last summer and has made 21 La Liga starts with the club.

El Mundo Deportivo reported on Monday that Suarez will return to Barca this summer and described the player as a must-sign for the team since his buy-back option is only €3 million.

"I have not spoken with Barca, perhaps they have spoken with my agent, I don't know.

"You never know, from here until the end of the season a lot of things can happen."

Suarez said he wouldn't be surprised if Barca did want him back.

"The possibility of returning to Barca is there and it's very difficult to say no to that," the 22-year-old midfielder said. "I've always wanted to play for Barca."
