The case against him is there for all to see.
We are definitely regressing as a club, the team don't even look capable of winning football matches right now. I'd actually put us down as dark horses for relegation considering our last 3 wins have actually came against the bottom 3 teams.
There's absolutely no game plan. The players go out there and basically just do what they like. Turning in and out on your own six yard box? Absolutely fine. Don't want to track your runner? That's not a problem either.
Anything we do well is just in spite of Martinez in my opinion. The good football we play isn't a byproduct of his management, it's just the fact we've got good players on the pitch.
