The team will get all the support they need for the semi mate.
You have much more knowledge of players and managers in the world than I have, but I've seen a lot of Everton managers come and go, and, baring a minor miracle, Martinez will be joining the lists of Bingham, Lee and, though it pains me to say it, Harvey. They all had half decent records at some time in their managerial careers at Everton, but, like Martinez, ultimately, they flattered to deceive. Martinez has had nigh on three seasons now, and we've had one good season in the league, and two poor ones.
He might have got away with that under the old regime, but I can't see him getting away with it now.
