Espanyol striker Raul de Tomas cannot rule out leaving this summer.
De Tomas is currently away with the Spain squad for their Nations League campaign.
He said, "Anything can happen.
"It is a decision in which people think one thing, the club another and I can think of a different one. Many things can happen.
"There will be clubs that will be interested, my own club may or may not want to sell me. This is a game. The markets they are like that.
"Perhaps the club is interested in making money with me, or I am interested in staying or going. Many people believe that my opinion is worth it.
"You have to give it naturalness. All three things can happen.
"There is concern everywhere. I want to enjoy myself and when this is over, the market will come and see what happens."
