Any manager who starts a season with 4 losses, conceding over 3 a game, should rightly be under pressure.If he doesn't get results immediately, and keeps conceding as he is then I agree.
I think he's rubbish and want a new manager. A couple of results won't change my opinion. But I don't think any manager has these results and performances, without being under pressure. Losing twice in a row from 2 up is totally unacceptable and unprofessional.
