It's the way we play we make team defend in how we have possession!
I reckon so. explanation behind it is we need much more shots overall per game to get the same amount of xG per game than someone like Arsenal or Liverpool.
our somewhat slower build up, pass around, backpasses, sideways stuff lets opponent to reshape and the bus parked in correct position, which means our shots are often has no chance to beat the first blocking defenders, or made from shit positions and number clear chances with high xG are very rare. (on the opposite side the chances we concede always are high xG still being converted in an immense rate even by lower table shit strikers)
Pool and Arse can afford to create 20-30-40% less shots and still score more goals as those chances are higher xG vs less organized defences being hit with speed quite often.
Liverpool-Chelsea few weeks back:
4-1 win for Pool at home, 2.9 xG for Pool, 4 goals and Nunez also hit the post 2 times, so comfortably overscored the xG due to some of those goals came from Chelsea defence were hit with pace and not fully set up
13 shots on target and 27 shots total from Pool
for us 1-1 result, 32 shots, only 5 on target with xG of 3, only one converted,xG heavily underscored, even that one goal needed a lucky deflection
Pool got 2.5 times more shots on target (exluding hitting the post 2x) from less shots overall.
