I rather like the idea of just waiting. Wait all summer, and appoint the new man about two days before the transfer window shuts in August. Then when they do appoint the new man, it's turns out to be someone who was available and ready to start back in May.
Marvellous. Go on Ivan.
I think Arsenal can go one better than that, using your timescale but how about a player-manager? :internalcheapsolutions:
