If this new management has any clue then they will sack him immediately.
CL next year is gone (not mathematically, but whatever), so there's that.
As in: no point really.
But we are still in the FA Cup final - against City. Winning that one would be pretty sweet - for everyone involved, I'd imagine: fans, owners, sponsors.
And I personally believe the possibility of us beating City in the FA Cup final (they can't do the treble, thank feck, but they will probably do the double if we don't beat them) is non-existent under ETH.
So, yeah.
Sack him now (take the hit financially), gamble on an interim - but for the love of Satan, do not consider that interim as anything beyond an...interim.
