While I wouldn't be upset to see Shez go, I don't see the point in sacking him given we have no money to pay him off and no money to give the new manager, plus the facts theres absolutely no-one I can think off to come in meaning Dux will get the job.
One point to take into account is that one play off team always gets relegated the following season, Hartlepool lost in the final and were relegated two seasons ago , Brentford got to the play offs and were relegated last year
