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 Porto's Alberto Costa at 23 years old has the highest Pre-Peak Value Efficiency at 20.00×. That means Alberto Costa is valued 20.00× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.
In second is Sporting CP's Iván Fresneda, who is 22 years old, with a 16.67× PPVE. Third is Diogo Travassos of Sporting CP, who is 22 years old with a 6.67× 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 20.00× means the player is worth 1900% more than typical players their age-making them high-value targets before they reach peak value.

Optimal Minutes: 2,500 per season (regular starter with rotation management)
1-Year Market Value Forecast
Probabilistic model combining age-curve depreciation, value momentum, and playing time factors:
• Age Factor: Compounding and banded around a peak of 28: +25%/year through age 21, +15% at 22-23, +10% up to the year before peak, then -5%, -10% and steeper with each later band. Growth is damped above €30M.

Our database tracks 21 Liga Portugal Young Right-Backs with comprehensive market valuations updated in October 2026.
How are Liga Portugal Young Right-Backs ranked?
Liga Portugal Young Right-Backs are ranked by our proprietary Analytical Strength Index, which is specifically calibrated for Young Right-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 Young Right-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 young right-back from the Liga Portugal?
Transfer fees for Liga Portugal Young Right-Backs vary significantly based on market value, contract length, and club bargaining position. For the top-ranked young right-back Alberto Costa (market value: €18.0M), estimated transfer fees would range from €14.4M to €25.2M 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. 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 Young Right-Backs?
Our 1-year forecast model projects market value changes for Liga Portugal Young Right-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.
