At the moment Madueke is quite literally our only first team option for RW so how is it stockpiling if we get another player who can play there?
For a 4-2-3-1 formation we basically have Jackson, Broja, Nkunku, Mudryk, Sterling and Madueke for the four starting places. Six players for four spots doesn't seem like a lot to me.
As for Michael Olise, I haven't seen enough of him to say if he's actually any good. Being out injured till late September at a minimum would make signing him kind of pointless though.
