I think he has to go. It's farcical now and while I think we pick up at least 4 points from Newcastle + Brighton at home, it's difficult to see how we get more than 2 points from the rest of the fixtures. We have enough points on that basis, and I still think 37 will be enough, Stoke have a tricky run in and it only takes 1 of the 6/7 sides to to get 7 points from 10 games which is very possible.
The risk is, firstly bringing a new manager in could still see us dragged into relegation mire. However sacking Allardyce at this stage would be a bold move. I think we give him the Brighton game at least, the season's been written off anyway and he should still lead us to safety.
The other point is, if he wants Fonseca, he will have to wait anyway. If we sack Allardyce we run the risk of being rudderless again. This is dangerous. It's not like under Martinez when we were safe but free falling. We are free falling from a points base of 34 points.
I know people want him gone, but in my view he will stay a while yet.
