TackleZone Goalkeeper Score
Rates goalkeepers on rating, save percentage and goals conceded — with an honest caveat about how much of that is the defence.
What it measures
Goalkeeping is the position where individual numbers are most contaminated by the team. A keeper behind a good defence faces fewer and worse shots and will concede less regardless of ability.
TGS leans hardest on match rating precisely because the counting stats are the most team-dependent of any position.
Components and weights
Match rating
45%
The provider's per-match rating, averaged across the season. Carries the most weight in every score because it is the only component that reflects things the counting stats miss.
Save percentage
30%
Saves as a share of shots faced. The core goalkeeping number.
Goals conceded per 90 (inverted)
25%
Inverted so fewer is better. Partly a team measure, which is why it is not the largest component.
Percentages are read directly from the live formula, so this table changes whenever the score does. Each component is normalised across the qualifying pool before the weights are applied.
Why it is built this way
Goals conceded per 90 is inverted so that fewer is better, and given the smallest share, because it is the component most driven by the players in front.
Save percentage treats every shot alike. A tap-in and a 30-yard effort count the same, which flatters keepers facing low-quality volume.
Who qualifies
900+ minutes in the season block and a match rating of at least 6.8. Players below either bar are not scored, because a per-90 figure drawn from a few hundred minutes measures luck more than ability.
What TGS does not capture
This is the weakest of the four scores and we would rather say so. Distribution, command of the box, sweeping and claiming crosses are all absent from the data, and they are a large part of modern goalkeeping.
Our provider sends a `goals_prevented` field that would fix much of this, but it returns the same value for both teams in every fixture we checked, so it cannot be attributed to a keeper and we do not publish it.
A busy keeper in a poor side can score well on save percentage while conceding heavily, and a keeper with nothing to do can score well on goals conceded. Read TGS alongside the minutes and the shots faced.
We publish this section because a score you cannot argue with is not worth much. If one of these limitations matters for the player you are looking at, weigh the number accordingly.
