As individuals neither appear to have the skill set to play as lone striker in the Premier League.
It’s rumoured that we’re after a new striker to fix this issue, but if we don’t get one I wonder if there could be merit in perhaps trying Mateta and Edouard together - at least against weaker opposition.
Playing two strikers has largely gone out of fashion in the Premier League, but Edouard can play coming in from the left (where we have a vacancy!) and also play off the striker.
Both seem comfortably marked out of games when played in isolation against opposition defences , but perhaps they would be afforded more space if there were two forwards for the opposition to be concerned with.
It’s not an ideal solution but we need to find a way of carrying more threat, in particular in the absence of Zaha and Olise.
It could even be used for spells in games; at the moment it’s either one or the other with one frequently being used to substitute the other rather than being utilised together.

My old memory might be tricking me but I think I recall the two of them doing well in the 2nd half against Liverpool in the home game in the 21/22 season when Mateta set Edouard up for our goal. We had the Scousers under a lot of pressure in that 2nd half until the awarding of that unfair penalty against Guaita in the dying minutes.

So you may have a point at least until Olise is back and Franca is up to speed (assuming we don't lose the latter to a last minute gazump)
