Zirkzee dazzles, United cruise 5-0: But what's Carrick *really* building?

Carrick's crew shook off that embarrassing Wrexham loss. They hammered Rosenborg in Trondheim, 5-0. What did we see? A manager clearly ditching his old ways. Remember that rigid, transition-first rubbish he started with? Gone. Or so it seemed. Before this, United were a counter-attacking machine. Third in fast breaks per game (1.53). Joint first in goals from them per 90 (0.24). Now? Against Rosenborg – a side 13 games deep into their own season, mind you – the Red Devils owned the ball. Composed. Even with Bruno Fernandes and Matheus Cunha nowhere to be seen. Who ran this new show? Zirkzee. He sat deeper. Dictated play. Pulled strings. The Dutch forward absolutely bossed receiving the ball, then spraying it around. Think about it: that's exactly why Carrick's apparently salivating over a Tielemans signing. The lad played 60 minutes. Assisted the opener. Bagged a second himself. Pure class. Shades of Dimitar Berbatov, even. But pump the brakes. Let's get real. Rosenborg were knackered. The scoreline was already cushy. All of it played right into Zirkzee's hands. Can he pull this off against proper Premier League defences? When the tempo's cranked up? And with other big names breathing down his neck? That's the million-dollar question. And for now, it's unanswered.
