The issue is this board. They want full control, and that was exactly why Tuchel was sacked, and since then, they've appointed "Yes" men. At this point, Enzo is no different despite initial impressions. That goes for your second point, too. Our team is built to develop talent, not challenge (feeder club mentality).
On a side note about Brighton's win, do people forget we destroyed the same team at the Bridge last time we played? Brighton didn't do anything special; we just offered nothing after scoring and made mistakes that gave them the win. If this was a PL game, their winner is probably chalked off for Lamptey's handball.
