You're right Torres was actually pretty clinical but he had to be as you've alluded too, if he was genuinely a poor finisher like Werner/Morata he would have scored about 5 for us if that.
My issue with Torres is he had not one positive attribute to fall back on, even at his worst Werner gives us pace and pressing, Morata gave us good movement, honestly what did Torres give when he was playing relitevely 'well' let alone poorly? What positive did he give us?
