We should purchase a player even if Tiago does not leave. What difference does it make is to our team if Tiago stays or goes? He's has been practically invisible for us. I'd even go as far as saying that even Almiron even made a bigger impact at the club, at least he was decent during pre season & some early coppa italia games, what has Tiago done? And signing a player that only played a single game last season for his club, and that has constant injuries is brainless. There are far better options than Appiah, in Moutinho, Lucho gonzalez, Rakitic, etc
