Exactly. Put Harry in the Chelsea side and he would soon look like a world beater again. Or any top side that actually creates chances for that matter.
We create next to nothing, game after game after game, against the better sides.
Our only hope in big games ( or honestly ... any games) for a long time has been Kane picks the ball up and plays Son in behind the defence. We obviously had that period under Jose where it was successful, but it's very predictable, and against a canny defender like T. Silva, predictable won't cut it.
And then the maybe 1-2 times a game it does come off, you're relying on Son being ultra clinical .. which whilst he's an elite finisher, isn't exactly going to work long term.
We just don't have players who pull defences out of their shape, or scare them. As much as Adama has no productivity, he would at least have been a curveball option who could make defenders uncomfortable.
