I don't think he's fully hit his stride yet this season, but 3 goals in 3 games is a scary return for a player playing at about 60%. I can already see everyone, City fans included, taking him for granted.
Likewise, think him and Alvarez will click at some point, they're still taking up each other's spaces (or not taking up spaces because they don't want to get on each other's toes). Think that might account for Haaland slightly lacking the killer instinct of always being in the right place, but the time to work that out is now.
I reckon he's rightly starting to get annoyed at defenders pinching him, prodding him, digging their fingers in. I don't think he needs "protecting" but I do think refs need to let him stand up for himself.
