Of course the board manage what happens on the pitch.
When your manager and top players sign contracts on the proviso that they'll soon be joined by more world class players, how can they be expected to stay motivated when it transpires they were lied to?
There reached a point when Liverpool stopped being run by football people and started being run by financiers with the remit to reduce debt whilst making the club as attractive as possible to potential investors/buyers. For the whole of 2010, nobody was interested in what was happening on the pitch. The bank wanted their money back, the owners wanted their profit, the supporters wanted the owners gone and the players wanted to leave.
And in the middle of it all was Rafa.
Don't get me wrong - I'm sure he made mistakes at Liverpool. But there is a mountain of mitigation.
Would you have Rafa back over Kenny?
