The New Coach Effect 

The positive effect a new coach has on his football team, immediately following his appointment.

A football team appoint a new coach after a run of poor form where the previous coach has either been sacked or has resigned from his position.

The mere change of coach is enough to turn the teams fortunes around, instantly. This is known as the new coach effect.
