Really not sure about this, he's a phenomenal player of course but I really don't think we need to reinforce the striker position, this just reminds me of past transfer windows where we keep buying more and more attacking players only for us to lose or draw numerous games because we refuse to reinforce our midfield and fullbacks.
Besides that this adds yet another attacking player who'll expect to start every game, I just can't fit all of Aguero, Aubameyang, De Bruyne, Silva and Sterling into one lineup.
