The appointment of a new head coach is often a time for hope and optimism. While the wrong hire will obviously draw criticism and frustration from the fanbase, whenever a new man is handed the keys to the car, there is a natural optimism that believes in his ability to make it drive.
Of course, there are some names that are more exciting than others. Montreal Impact fans are likely much more excited about Thierry Henry than they ever were about his predecessor, Wimer Cabrera.
But such is the importance and influence of a head coach at a football, it is almost always possible to talk yourself into believing that arrival of a new voice and leader is all the team needs for revival.
