Actually, we have more shots and more shots on goal this season per PL game when playing 4231 than we had during our unbeaten run from 1 February onwards last season - 16.1/5.9 this year, versus 13.5/5.5 then. There's actually been just one game with that formation where we had fewer than 4 shots on goal (Tottenham, 2), plus the Arsenal game when we played 442 diamond (also 2).
Goals in CL/PL games are pretty evenly spread between penalty/set pieces, counterattack goals and established play goals.
Stats aren't everything, but they certainly don't support your opinion either.
Sorry, what? That's just laughable.
Liverpool has a world class squad. And what is more, the system they play
requires a world class squad to implement. They play with extreme risk - high pressure, high defensive line, and total attacking commitment by the full backs. A normal team plays like that, they get hammered 4 times out of 5. It's not a system that makes poor players good, it's a system that allows very good players to have maximum effect.
