I hope he doesn't go on loan either, It's just my feeling. I don't even know if Tosin is staying lol. I know he got a new contract and all but I'm not sure.They are in his way though because Zidane chooses between 442 and 433 based on the personnel he thinks are up for it.
So Mariano is competing with the wide players too, trying to get Zidane to put him in a 442 or 41212 as opposed to going with wide players like Assensio or Bale.
Diaz could go on loan, but I just don't think he will, I think they'll try to keep him close like Tosin and bring him through without loans.
