How clubs are assessing managers and why United will be judging Solskjaer on more than his win percentage
The evolution of data in football has barely taken a pause for breath in the previous decade, but one area the numbers have been slow to infiltrate is in how we assess the performance of a manager.
The data-led revolution has changed the way we think about players and performance, giving metrics that can support what we see with the naked eye, or make us question our own wisdom.
But when it comes to managers the mainstream conversation rarely moves beyond win percantages. When a manager is sacked his win percentage will be mentioned, often compared with his predecessors through one of those nifty Sky Sports News graphics, but how much is that really telling us?
For example, according to win percentages David Moyes was a better Manchester United manager than Louis van Gaal. Is that a fair assessment? Not many United fans would agree with it.
