Why can't Liverpool score?

James Benge uses TruMedia’s ProVision platform to analyze Liverpool’s scoring issues and how Mo Salah’s role has changed this season:

“This season that has changed somewhat with Salah forced to drop ever deeper in pursuit of the ball, as his heatmaps indicate.

Equally, because he is operating from deeper he is now taking 28 percent of his shots from outside the box having not even attempted 17 percent the season before. The same is true, to a lesser extent of Mane and Firmino. Without a flawlessly functioning system behind them the front three are having to do more and deal with less – it is notable as well that those two have been taking far more headed shots than in years gone by. If the full-backs are having to put in more crosses from low percentage positions then naturally the likes of Firmino and Mane will be attempting more headers and fewer high-percentage shots on their strongest foot.”
