Getting rid of him now would probably further destabilise a club that is already on the brink of being in crisis. If we don't go up, I think it'll be panic stations all round.
However, if we do go up, I think he has to go. On too many occasions this season he's been out thought by Championship quality managers such as Robins and Farke (not to mention whoever manages QPR, Bristol and Plymouth).
Those aren't moans because we lost to these teams, it's a moan because on each occasion they had done their homework on our plan A, developed a decent plan to deal with our attack and countered us. We've seen it happen often, but where as the opposition has a plan to deal with our plan A, we've failed to develop (or even consider) a plan B.
Should we make it to the Premier League now, we'll be starting with a points deduction. To comply with the financial rules, we're going to have to assemble a squad on a budget that'll make Mickey's Misfits look like the galácticos. Which is going to require a siege mentality, ability to play through a potentially hostile home atmosphere and a heap of different approaches to winning a football match and I don't think Enzo is capable of that based on what we've seen.
