Statistically speaking (based on the difference between post-shot expected goals and actual goals conceded - i.e. how good a goalkeeper is at stopping shots), Emi Martinez was the 6th best keeper in the league last season and is currently 4th this season. The season before last he was 16th. On another important metric for the modern goalkeeper - distribution, he’s extremely average. He’s 14th in the league for long pass completion this season, was 13th last season and 11th the season before. The one area he truly excels is claiming crosses. He’s currently ranked 3rd for percentage of crosses stopped, was 1st last season and 6th the season before.
