I have the same doubts. I mean, the rest of the teams that we could get aren't really much themselves but the same has to be said about us as well.
Not really. I don't think performances improved too much from early on (even though I never thought, they were too crazy bad under Amorim to begin with), we still aren't comfortable on the ball, we still have mistakes and concentration lapses in us and creating chances wise we are pretty much back to individual brilliance with only one player in the team able to display some of said brilliance.
I agree with you, we looked decent to even good against better teams but to win EL, we won't play against better teams. We look usually fairly bad against teams that are around our own level and were set up to hit our weaknesses. There isn't much to expect Lyon, Fener or Spurs to try to play a dominant game like Arsenal or Liverpool against us.
Don't get me wrong, I dont want to put a dampener on things, I was never crazy worried about performances since Amorim is there but I don't see the level having changed too much apart from certainly going down a notch with Amads injury. I think, the other poster is right, we are just one bad result away from many fans go into doom mode again so much of the latest optimism is down to some good results rather than a promising uptick in performances.
