1. What is Goals Scored Against (GSA)?

Goals Scored Against (GSA) is a key statistic in soccer and other sports that measures the total number of goals a team has conceded over a period of time or number of games. It's an important metric for evaluating defensive performance.

2. How Does the Calculator Work?

The calculator uses the GSA formula:

Where:

• \( GoalsAgainst_i \) — Goals conceded in game i
• \( n \) — Total number of games

Explanation: The calculator sums all goals conceded across multiple games and can also calculate the average goals against per game.

3. Importance of GSA Calculation

Details: Tracking goals against helps teams analyze defensive weaknesses, evaluate goalkeepers, and compare performance across seasons or against other teams.

4. Using the Calculator

Tips: Enter the number of games and a comma-separated list of goals conceded in each game. The calculator will compute both total and average goals against.

5. Frequently Asked Questions (FAQ)

Q1: What's a good GSA in soccer?
A: Lower is better. Top teams typically average less than 1 goal against per game over a season.

Q2: How does GSA differ from clean sheets?
A: Clean sheets count games with 0 goals against, while GSA measures total goals conceded.

Q3: Should GSA be adjusted for game minutes?
A: For advanced analysis, some adjust for minutes played (e.g., when a player is substituted).

Q4: What other stats complement GSA?
A: Shots against, saves percentage, and expected goals against (xGA) provide additional context.

Q5: How does GSA relate to team success?
A: Teams with lower GSA generally perform better, though must be balanced with offensive production.
