yes its not like Haaland is missing sitters or any kind of good chances in large number. he does not have the chances lately...
we have lost a bit of mobility and our pressing not as good with Haaland but that also comes from KDB having fitness issues, Bernardos form alongside Cancelo's dropping off a cliff generally and other players have form issues too like Foden...
changes need to be made by Pep in our way of playing/building attacks to accomodate Haaland more, issue is that would may come by having less control which is something Pep will never want to give up.
Haaland is one of the best striker for a team playing for the transition, quick counters, able to beat a high line defence, but we prefer to control the game, slow the pace and rather keep attacking vs a reorganized block of 10 men parked bus than quicker attacks which can cause us lose the ball bit more often.
I think problem is the defence, Pep has not much trust in our defending, hence the control freak tactics. and he is not wrong on that, we need about 2 dangerous run at our defence to certainly concede 1 or two goals on average.
look at today game, they had about 3 dangerous attacks, one where Ederson was mental coming out badly, one the offside goal and their winner.
