I can't speak for Schulz, but I can say I am very much a fan of the team, but getting very apathetic to the leadership. Watching this team just constantly do the same thing over and over and getting these results is just frustrating.
You see a post like Derka's in the EPL thread (the one on the last 3 managers) and you see the difference between a team with no plan (Spurs) and teams with plans. The other 3. Conte and Mou are both at clubs where they have a lot of talent relative to the league. Forest, a team that was setup to play Defend and Counter, brought in the manager specifically for that and with great results. Spurs plan is ... What exactly? Buy our way to something? When we don't spend money?
If I were Levy, the real play should be: This season is lost because of all of our injuries. We have 2 goals now: Win 1 or multiple of Carabo, FA or Europa League and Don't get relegated. So long as we aren't relegated, you're coming back next year. And we'll bring in some pieces to help now and in the long term.
