Nothing weird about that, it's just reality. But of course, I hope that I'm wrong.
Silva will have more suitors then Krasic, Silva will cost more, financial trouble or not, which is overplayed too often (see Villa), he will be hard to get still.
But if we say, costs 20m (Valencia rejected more then that already), Silva will be harder because he wants to stay in La Liga, and will have most top teams going after him. Krasic will also have suitors, and wont be easy, but weird to think he is impossible, and Silva is somehow easy.
