We have improved a lot. Under Bruce we were rock bottom in November 2021 having not won a single game, or even looked like winning a game. We are now playing CL football, and I assure you the majority of the fan base don't care at the moment if we're losing to teams like Dortmund. The weekend was frustrating of course, but it happens.
We are struggling at the moment due to injuries - at the weekend we had to start Lewis Miley, who is 17, in the core of our midfield. We had no fit striker. We're bringing on Matt Ritchie in 2023. Yes these are "excuses", but there comes a point where excuses just become "reasons" if you're rational about it. It's the same for other clubs too, and other clubs in the same position have struggled as well, even those with billion £ squads.
