It's complicated to buy when you've got the talent we already have. Just my opinion, but in a lot of positions we have so many high quality players, that I imagine it is hard to add more without selling.
Was talking to someone yesterday about the 9 position as an example. We need someone who is prepared to sit on the bench when Kun is fit, not demand to play every game, but also be better than Jesus and be even more consistent than Jesus in his goal scoring. It's just not that simple.
My worry with Auoar is simply that I don't want anyone signed in CM until it's established what Phil's role will be. For me he's an 8, and adding Torres means we will need him less in the front 3. If we're going to play Phil/KDB a lot, then we don't need another midfielder unless we're selling one IMO.
