We want the money. In order to spend big we have to sell big.
We'll see, I don't know, but I don't see Sandro staying. Actually I'll be surprised if he stays here. But even if he does stay, I think he's bound to leave next summer. I was talking the same about Pogba and people laughed at me. Year and a half later we sold him. I just can't see Sandro staying here.
It's a horrible and sad thing. With this move (IF HAPPENS) we're just showing that we're not a top club. We're just an enchanted Dortmund. Sure, we reach CL finals, or at least we did over the past 3 years. But we're one of the clubs, just like Dortmund, who can't keep their best players while at the same time you can expect us to sign bright starts but just to shape them enough for top clubs, like Real or Bayern. Or even EPL money filled clubs like Chelsea or City.
