Jack is not in the team to score goals, Yes they all add up but Jack does more for the team than anybody else
He's the one player that makes the room for that little pass back into the middle, Normally its to KDB
Also Jack brings 3 players over to him and again Pep the master Knows the space that Jack makes for others is so valuable to all of Pep's plans,
The amount of stick Jack gets is so funny because nobody ever thinks what he brings to the team, Even if he does not score, The little things like winning a throw-in or a foul or like I said that little pass to KDB leads to City creating chances,
