Okay, I'll give you Calvert Lewin.
We signed Stek and Williams because longer term solutions weren't available at that time. It's not exactly easy to replace a young centre half with 22 days left of the window. I'm glad they didn't waste money on players they weren't sure about.
DoF and scouting teams plan their signings 2 to 3 transfer windows in advance. People keep ignoring this. We didn't just sack the manager, we brought in a whole new backroom and scouting team. Massive upheaval at the club, during a Euros summer when transfer activity was largely limited across all club until commencing late July/early August.
