Silva would be less of a risk then Diego, and quality are more or less the same with them, except Silva being more versatile to say the least. But I havent really thought of Silva because really, I dont see him as realistic signing. I hope love it if Secco could suprise us, but I mean, if Silva is on the market, you will have Barca, Real, Chelsea and such all seriously gunning for him BIG TIME.
Its likely he will leave despite how hard they are trying to conceal their big financial troubles, but sadly, Silva will be too sought after.
