We are decent in possession but pathetically bad out of possession.
Whether that's our counter press after we lose the ball which is non existent and leaves us so open to counters.
Or the movement off the ball when we are in possession. No one breaks the lines. No one drifts in and out of the half spaces. Etc
Both of the above were so key to us being a success during the (possession based) positional style of play under Maresca.
Fix the above, and I think this style can work. And all it needs is good coaching and a hunger from the players to work hard on the pitch.
