He seems like a genuine bloke, who wanted to help but ultimately wasn't good enough.
Appreciate we are a basket case of a club off the pitch, but his job is to do the best he can on the pitch. Three key measures of a manager (aside from the obvious winning of games) are recruitment, tactics and man management. He failed badly on all three counts.
Whoever is appointed tomorrow, if they are only an interim until the end of the season, then please please please can someone take responsibility for finding the manager for next season as soon as possible so they have the chance to assess the squad and line up potential signings ready for summer.
