Pre-Peak Value Efficiency (PPVE)
Identifies pre-peak players offering exceptional value relative to their age bracket. Higher PPVE = better value.
Understanding Pre-Peak Value Efficiency (PPVE)
FC Alverca's André Gomes at 21 years old has the highest Pre-Peak Value Efficiency at 10.00×. That means André Gomes is valued 10.00× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.
In second is SC Braga's João Carvalho, who is 22 years old, with a 5.00× PPVE. Third is Diego Callai of Sporting CP, who is 22 years old with a 4.00× PPVE.
How PPVE is calculated: PPVE compares a player's current market value to the median value of all players in their age bracket. A PPVE of 10.00× means the player is worth 900% more than typical players their age-making them high-value targets before they reach peak value.

Return-to-Peak Potential (RPP)
Recovery potential from current value to forecasted peak. Shows how much upside remains for players approaching their prime.
Understanding Return-to-Peak Potential (RPP)
CD Santa Clara's João Afonso at 19 years old has the highest Return-to-Peak Potential at +55%. That means João Afonso is projected to appreciate 55% as they reach their peak age in 7 years-representing significant upside before entering their prime.
In second is SL Benfica's Diogo Ferreira, who is 19 years old, with a +55% RPP (7 years to peak). Third is Gui of Vitória Guimarães SC, who is 20 years old with a +52% RPP (6 years to peak).
How RPP is calculated: RPP compares a player's current market value to their forecasted peak value, calculating the percentage appreciation potential. A 55% RPP means the player is expected to gain 55% value as they enter their prime-making them excellent growth investments.
Recovery Potential by Player

Risk-Adjusted Upside (RAU)
Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)
Sporting CP's Francisco Silva has the highest Risk-Adjusted Upside at 76.5. That means Francisco Silva has 16% upside potential with only 0% forecast uncertainty-representing excellent risk-reward for value appreciation.
In second is CD Santa Clara's João Afonso with a 76.5 RAU (16% upside, 0% uncertainty). Third is Gonçalo Ribeiro of FC Porto with a 76.5 RAU (16% upside, 0% uncertainty).
How RAU is calculated: RAU divides upside potential by forecast uncertainty (RAU = Upside % ÷ Uncertainty %). A RAU of 76.5 means the upside is 76.5× greater than the uncertainty-making it a high-confidence growth opportunity. Target RAU ≥2.0 for balanced risk-reward.
Risk-Adjusted Upside by Player

Roster Pressure Index (RPI)
Squad depth pressure based on Z-score distribution. Negative RPI = thin depth, positive = deep roster.
What This Shows
Z-Score explained: Measures how many standard deviations a player's strength is from the position average. Z-Score = 0 means average, +1.0 is one standard deviation above average, -1.0 is below average.
How to use: RPI < -1.0 indicates critical depth shortage. These positions need immediate reinforcement. RPI > +1.0 suggests strong depth, allowing selective, high-value additions only.
Current market: young goalkeeper position shows weak depth (avg Z-score: -0.00). RPI: -0.00.

Age-Share Concentration (ASC)
Identifies players capturing disproportionate value relative to age group representation. Positive ASC = value concentration.
Understanding Age-Share Concentration (ASC)
CD Nacional's Kevyn in the 21-23 age bracket has the highest Age-Share Concentration at +-5.9%. That means André Gomes captures 69.1% of total market value while representing only 75.0% of players in their age group-showing dominant elite status.
In second is Vitória Guimarães SC's Juan Castillo with a +-5.9% ASC (69.1% value share vs 75.0% player share in 21-23 bracket). Third is André Gomes of FC Alverca with a +-5.9% ASC (69.1% value vs 75.0% players in 21-23 bracket).
How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +-5.9% ASC means the player captures -5.9% more market value than their numerical representation-indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
Value Concentration by Player

Frequently Asked Questions
Common questions about Liga Portugal Young Goalkeepers in the 2023-24 season
Who are the most valuable Young Goalkeepers in the Liga Portugal in 2023-24?
The most valuable young goalkeeper in the Liga Portugal in 2023-24 is André Gomes, who is worth €3.0M and plays for FC Alverca. The second most valuable is João Carvalho (€1.5M, SC Braga), followed by Gonçalo Ribeiro (€1.5M, FC Porto). Our database tracks 20 Liga Portugal Young Goalkeepers with comprehensive market valuations updated for the 2023-24 season.
How are Liga Portugal Young Goalkeepers ranked?
Liga Portugal Young Goalkeepers are ranked by our proprietary Analytical Strength Index, which is specifically calibrated for Young Goalkeepers. The score combines six factors: Historical Achievement Index (35%) measuring peak career value, Current Performance Proxy (30%) reflecting recent market signals, Playing Time Utilization (18%) tracking minutes played, Age-Adjusted Performance Curve (12%) using position-specific peak ages, League Quality Coefficient (3%) for Liga Portugal competition level, and Club Tier Multiplier (2%) accounting for club prestige. This methodology is grounded in academic research including work by Dendir (2016) on age-performance curves and Franck & Nüesch (2012) on hedonic pricing models.
What age do Young Goalkeepers peak?
Goalkeepers typically peak at age 30, later than outfield players. In our valuation model, value then falls in widening steps rather than at a flat annual rate: around -5% in the first year after peak, -10% in the second, and steeper again from 33. This is supported by research from Dendir (2016) showing that goalkeepers maintain elite performance longer due to the position's reliance on positioning, decision-making, and experience rather than pure athleticism. The optimal playing time for peak performance is around 2,700 minutes per season.
How much does it cost to sign a top young goalkeeper from the Liga Portugal?
Transfer fees for Liga Portugal Young Goalkeepers vary significantly based on market value, contract length, and club bargaining position. For the top-ranked young goalkeeper André Gomes (market value: €3.0M), estimated transfer fees would range from €2.4M to €4.2M depending on contract situation. Players with longer contracts (3+ years) command premium fees (1.2-1.4× market value), while those in the final year may be available for 0.8-1.1× market value.
