Lose tomorrow and put money on him not making it to goodison.
If the board are planning on replacing him anyway, imagine keeping that manager to go to goodison after both the derby and no fa cup final?
In all fairness these two games should have been a bench mark. the fans care about beating liverpool (even me deep down) and the fa cup marks success for the club. So to have given him the chance in both of them is a fair oppertunity from the club. If he fails both then he can't continue in the role, the fans would be too hostile, especially at goodison. The knock on effect would be huge, we struggle at home v bournemouth with our terrible home record, lose again, more negativity seeps in, more fans hostility etc
Hell even season ticket sales, for those not sold, would there be a massive clamour to buy them if martinez was unsure to still be here next season after this one?
