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)
Sporting CP's Ousmane Diomande at 22 years old has the highest Pre-Peak Value Efficiency at 42.00×. That means Ousmane Diomande is valued 42.00× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.
In second is Sporting CP's Gonçalo Inácio, who is 25 years old, with a 40.00× PPVE. Third is Tomás Araújo of SL Benfica, who is 24 years old with a 30.00× 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 42.00× means the player is worth 4100% 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)
CF Estrela Amadora's Otávio at 20 years old has the highest Return-to-Peak Potential at +44%. That means Bastien Meupiyou is projected to appreciate 44% as they reach their peak age in 6 years-representing significant upside before entering their prime.
In second is FC Famalicão's Vojin Serafimovic, who is 20 years old, with a +44% RPP (6 years to peak). Third is Bastien Meupiyou of FC Alverca, who is 20 years old with a +44% 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 44% RPP means the player is expected to gain 44% value as they enter their prime-making them excellent growth investments.

Risk-Adjusted Upside (RAU)
Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)
CF Estrela Amadora's Otávio has the highest Risk-Adjusted Upside at 40.4. That means Otávio has 10% upside potential with only 0% forecast uncertainty-representing excellent risk-reward for value appreciation.
In second is SL Benfica's Gonçalo Oliveira with a 40.4 RAU (10% upside, 0% uncertainty). Third is Henrique Silva of CD Santa Clara with a 40.4 RAU (10% upside, 0% uncertainty).
How RAU is calculated: RAU divides upside potential by forecast uncertainty (RAU = Upside % ÷ Uncertainty %). A RAU of 40.4 means the upside is 40.4× greater than the uncertainty-making it a high-confidence growth opportunity. Target RAU ≥2.0 for balanced risk-reward.

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: centre-back position shows strong depth (avg Z-score: 0.00). RPI: 0.00.

Lowest Z-Scores
Age-Share Concentration (ASC)
Identifies players capturing disproportionate value relative to age group representation. Positive ASC = value concentration.
Understanding Age-Share Concentration (ASC)
Sporting CP's Sebastián Coates in the 30+ age bracket has the highest Age-Share Concentration at +-36.0%. That means Jan Bednarek captures 14.4% of total market value while representing only 50.4% of players in their age group-showing dominant elite status.
In second is Moreirense FC's Abdoulaye Ba with a +-36.0% ASC (14.4% value share vs 50.4% player share in 30+ bracket). Third is Freire of GD Chaves with a +-36.0% ASC (14.4% value vs 50.4% players in 30+ bracket).
How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +-36.0% ASC means the player captures -36.0% more market value than their numerical representation-indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
Value Concentration by Player

|---|---|---|---|---|---|
| #1 | Sebastián Coates Sporting CP | 30+ | 14.4% | 50.4% | -36.0% |

How are Liga Portugal Centre-Backs ranked?
Liga Portugal Centre-Backs are ranked by our proprietary Analytical Strength Index, which is specifically calibrated for Centre-Backs. 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 Centre-Backs peak?
Defenders typically peak at age 28. In our valuation model, value then falls in widening steps rather than at a flat annual rate: around -5% at 29, -10% at 30, and -25% or more from 31. Research shows defenders balance physical attributes with tactical intelligence, allowing them to maintain high performance through their late 20s. The optimal playing time for peak performance is around 2,500 minutes per season.
How much does it cost to sign a top centre-back from the Liga Portugal?
Transfer fees for Liga Portugal Centre-Backs vary significantly based on market value, contract length, and club bargaining position. For the top-ranked centre-back Gonçalo Inácio (market value: €40.0M), estimated transfer fees would range from €32.0M to €56.0M 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. Our fee estimates are derived from historical transfer patterns and contract-clock modifiers validated against actual Liga Portugal transactions.
What is the value forecast for Liga Portugal Centre-Backs?
Our 1-year forecast model projects market value changes for Liga Portugal Centre-Backs based on age-curve depreciation, historical trajectory, and playing time adjustments. The forecast combines three factors: age-based appreciation/depreciation (pre-peak players compound gains toward their position's peak age, up to +25% a year through age 21 and easing as they approach it, while post-peak players fall in widening steps), market trajectory momentum (comparing current to peak value), and playing time confidence (regular starters receive +2% boost). Forecast confidence intervals account for position-specific volatility-defenders have ±10% volatility. Young players (under 22) and older players (over 32) receive 1.15× uncertainty multipliers due to unpredictable development or decline patterns.
