Analyzing coaching perspectives

I’m thinking about how a coach, like Allegri, might respond to claims that a team's win is due to luck or exceptional saves. He might emphasize that the goalkeeper is a crucial part of the team's strength. You can’t just swap keepers mid-game, as that introduces complexity; each team has its own goalkeeper. Critics may argue that good performance is luck, but Allegri would assert that it reflects the team's overall quality. In football, variances exist, and a goalkeeper's overperformance certainly impacts expected goals.Evaluating goalkeeper performance

I’m considering how a goalkeeper's shot-stopping reflects skill over time, measured by metrics like PSxG-GA (post-shot xG minus goals allowed). When a goalkeeper saves more than expected, it’s usually due to training and skill, not luck. Attribution solely to luck ignores the nuances of performance. I can propose two perspectives: short-term variance versus long-term skill. I should also suggest assessing performance using metrics like save percentage and the quality of saves to gain a balanced view.
