Diogo Costa is a 26-year-old goalkeeper at FC Porto, rated 63.5 overall by Field Insider's model, ranking 43rd of 317 in the Primeira Liga. In his prime years, he has been an ever-present this season (95% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Costa.
Judged on this season alone, Costa graded 88 — a standout campaign that ranks top 5% of the 24 goalkeepers in the Primeira Liga, on 20 clean sheets across 33 appearances.
Year-on-year, that's a clear step up on last season (Season 67 → 88). Across the 6 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 64, top 25% of the 24 goalkeepers in the Primeira Liga. At 26 Costa is in his prime years, and a market index of 40.4 reflects that trajectory.
A career still climbing — Costa is at his peak right now, and the curve hasn't flattened.
20 clean sheets in 33 appearances (61% of games). Playing behind a title-challenging side (1st of 18) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.
With a Rating of 63.5, Costa carries the 6th-highest potential of the goalkeepers in the Primeira Liga (top 25%). A near ever-present keeper carrying the gloves this season. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
Generated from Field Insider's rating model · AI-written analysis to follow.
The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~40), then tapers with age. At 26, Costa sits on 40.4, at or near its peak. The blue line is Costa's projected Rating — 63.5 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
