If he signs Where do Sterling, Nolito, Sane, Moreno, Gabriel Jesus, Roberts & Brahim fit into this in 2017-18.
It's a no for me.
I get the feeling Nolito is a short term signing an I wouldn't be surprised to see him sold next season. Brahim will still only be 17 next year so won't demand place in the first team squad. Some of these young players being brought in will likely be sold on for profit, not all of them are going to develop into world beaters anyway. I also think it's going to be Sane OR Aubameyang as I think Pep sees Sane as able to play as a striker.
17/18 front line:
Sterling/Jesus - Aguero/Iheanacho - Sane/Moreno
The amount of talent we're going to have in these areas is unbelievable if they develop properly.
