Think everyone has to share some blame.
Haaland, in games where he feels he isn't getting the service he needs to start forcing it. Drop deep, run channels, hold on to ball to allow overlaps
Pep and his teammates(bar Kev). Pep has coached us to become very risk adverse and that's for better and worse impacted players overall game. Attempt a low percentage creation opportunity or keep probing with low probability of conceding possession? They choose the latter almost everytime.
Few things, vs well drilled teams this is extremely boring to watch and most of the time reverts to us being a cross and hope team. Also, so many of our chances recently seem to be coming from set pieces? From open play we're just not nearly as effective as we once were.
The fix, everyone needs to do their bit. Pep, sacrifice a few possession % numbers in favour of more variety to our attacking play.
Erling, mix his game up. Make 3 runs in behind and teammates ignore each one? try something different instead of running in behind a 4th time. Rest of the team, in correlation to Erling, get your heads up and look beyond who is available to the side. Increase speed and fluidity to the build-up. Moving it at a snails pace at times.
