Atletico Madrid president Enrique Cerezo refused to rule out moving for Real Madrid midfielder Wesley Sneijder.
After successfully navigating their Champions League qualifier against Panathinaikos, Cerezo admitted the new cash arriving could be put towards new signings before the summer market shuts.
"The squad is still not complete, there may still be some opportunities to buy," said Cerezo. "If there is an opportunity with Sneijder, I have no doubt that we will do everything to get him.
"At the moment we are thinking about it. In football, anything is possible."
