If an overpriced Callum Wilson or over 30 on huge wages Higuain are our only options, then we really are missing Emenalo or some other scouting/planning support.
I'll say it again, after the Torres debacle and up to Mourinho version 2, we made better decisions in the transfer market. Not perfect, but better. We bought in the likes of Lukaku, De Bryne, Salah, Oscar, etc. Players that weren't known about at the time and while we screwed up developing them at Chelsea, they all went on to either give a transfer profit or embarrass us by turning out really really good at other clubs.
We need to go back to that system. The one that scouts and buys players before they reach potential. It won't always work out, but bang for buck we were doing better before Mourinho and Conte came in and made generally horrible decisions in the transfer market that is responsible for the mess we are in now.
I know this view still probably isn't very popular, but the director of football model where the manager wasn't making so many decisions in the market worked for us (for the most part).
But anyways, in the meantime, Higuain might be a decent stop gap.
