The way I judge an attacking player is what skillset do they possess if they lose their pace (possible serious injury)? Our best players across the pitch - Isak (finishing), Tonali (anticipation, set pieces), Bruno (press resistance, through balls), Botman (heading, passing, anticipation).
Even Barnes (elite finishing) and Murphy (crossing, shooting),albeit an inferior player, offers more attacking threat if pace is impacted.
Gordon is becoming predictable without the likeability factor of our other players. Although I feel he can improve further and we shouldn’t seek to actively sell him, if there is a deal to be done we should take the money - more LW options out there in the market.
