Their midfield buildup was actually pretty slick but they kept overcomplicating inside the box instead of taking the early shot. If they just let it rip from the edge of the area more often they'd convert some of that possession into actual goals.
Honestly the biggest flag for me is how they react to a deflected clearance or a bouncing ball in the box. Normal sides panic or snap at it, clinical ones jusst stroke it into the side netting like it was a training drill. Makes me trust live betting on goals much more.
Dodgy officiating always births stories, and people latch onto narratives when no concrete evidence exists. Next time it happens in a live match, check if you can bet the over on cards real quick, that aloone pays for the chat show drama.
