Caps & goals this season.
K. Tzolakis is a 23-year-old goalkeeper at Olympiakos Piraeus, rated 45.9 overall by Field Insider's model, ranking 1st of 262 in the Super League 1. An emerging talent, he has been an ever-present this season (100% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Tzolakis.
Judged on this season alone, Tzolakis graded 76 — a standout campaign that ranks top 5% of the 22 goalkeepers in the Super League 1, on 19 clean sheets across 31 appearances.
Year-on-year, that's a clear step up on last season (Season 48 → 76). Across the 6 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 46, top 5% of the 22 goalkeepers in the Super League 1. At 23 Tzolakis is still climbing toward his ceiling, and a market index of 12.1 reflects that trajectory.
A career still climbing — Tzolakis is at his peak right now, and the curve hasn't flattened.
19 clean sheets in 31 appearances (61% of games). Playing behind a title-challenging side (2nd of 14) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.
With a Rating of 45.9, Tzolakis carries the 1st-highest potential of the goalkeepers in the Super League 1 (top 5%). A near ever-present keeper carrying the gloves this season. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
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 (~12), then tapers with age. At 23, Tzolakis sits on 12.1, at or near its peak. The blue line is Tzolakis's projected Rating — 45.9 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.
