Diego Simeone has sparked further speculation that Edinson Cavani could be on his way to Atletico Madrid. Simeone: "I've said many times; until the market is closed, there are always options. But I won't speak about players who aren't at the club. As for Diego Costa, well, I've spoken millions of times about him, the important thing is he is a part of our team. "Until October 4, I can't be sure of anything. This is football. The market is open so there are many possibilities. At midnight that night I'll tell you."
