I'll start with Di Maria. His departure right now is not going to happen. Carlo has switched to a 4-3-3, and Di Maria has been playing as the 3rd player in midfield. He could end up back on the bench next season though when Madrid go for players like Gundogan and Pogba, to add to Modric and Alonso/Illaramendi in the starting XI. As for Reus, we had a settled trio last season also, but Willian became available and we had to buy him. And Reus is better than Willian, not to mention Oscar. It's unlikely to happen though tbh, i think ideally Mourinho wants a left footed player.
