Below: strengths, watch-points, market-value outlook and the latest transfer news on Hartel.
Judged on this season alone, Hartel graded 37 — an excellent campaign that ranks top 14% of the 74 attacking midfielders in the Major League Soccer, on 9 goals and 4 assists in 34 appearances (0.387 involvements per 90).
Year-on-year, that's a clear step up on last season (Season 18 → 37). Over the 6 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 30, 49th of 74 of the 74 attacking midfielders in the Major League Soccer. At 30 Hartel is into the veteran stage, where the age curve weighs on the projection, and a market index of 7.7 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
9 goals in 34 appearances (0.26 per game), a meaningful share of the load for a relegation-threatened side. He also laid on 4 assists, so the all-round involvement reads 13 goal contributions (0.38 per appearance).
With a Rating of 29.5, Hartel carries the 49th-highest potential of the attacking midfielders in the Major League Soccer of 74, and he is posting that for a relegation-threatened side (St. Louis City finished 13th of 15) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. In the final third he profiles as a productive contributor (0.39 goal contributions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).

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 (~15), then tapers with age. At 30, Hartel sits on 7.7, past its peak and easing. The blue line is Hartel's projected Rating — 29.5 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.
