Perhaps counterintuitively, the defensive players we've added have made a big difference in this regard. Alisson, Trent, van Dijk, Gomez, Robertson, and Fabinho are all very good passers of the ball which draws out the opposition a little bit, and allows us to get the ball in dangerous positions much quicker. They're also snuffing out attacks earlier and winning the ball higher up the pitch than the players they replaced, meaning we're spending more time on the front foot and putting the opposition under pressure that eventually tells. @LFCMike mentioned our defensive improvement, which is obviously massive, but I think the contribution those same players make to the attack is overlooked sometimes.
