I propose we should put every manager and his team on annual renewal contract. Just give them automatic 10% increment until they are sacked.
When Mourinho was given a raise, you know what. When Ole was confirmed as permanent manager, we fell off the cliff. When Ole got a new contract, lighting came at speed of light.
In fact, every time when our players got a new contract, their performance went straight to Championship level. OK we need contract to tie down a player, so can't do much about 3-5 years contract.
