J. Harrison is a 29-year-old winger at Fiorentina, rated 45.5 overall by Field Insider's model, ranking 302nd of 385 in the Serie A. An experienced operator, he has been a rotation option this season (45.3% of available minutes). He brings 0.37 goal contributions per 90 (0.09 goals, 0.28 assists). Below: strengths, watch-points, market-value outlook and the latest transfer news on Harrison.
Judged on this season alone, Harrison graded 20 — a workmanlike campaign that ranks 21st of 35 of the 35 wingers in the Serie A, on 1 goal and 3 assists in 15 appearances (0.368 involvements per 90).
Year-on-year, that's a clear step up on last season (Season 8 → 20). Over the 6 seasons on record his form has drifted down, peaking in 2020/21.
On long-term talent our Rating reads 46, 29th of 35 of the 35 wingers in the Serie A. At 29 Harrison is in his prime years, and a market index of 43 reflects that trajectory.
Past his 2020/21 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
1 goal in 15 appearances (0.07 per game) — light end product the role wants to see climb. He also laid on 3 assists, so the all-round involvement reads 4 goal contributions (0.27 per appearance).
With a Rating of 45.5, Harrison carries the 29th-highest potential of the wingers in the Serie A of 35, and he is posting that for a lower-table side (Fiorentina finished 15th of 20) — 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 (0.37 goal contributions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× 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 (~78), then tapers with age. At 29, Harrison sits on 43, past its peak and easing. The blue line is Harrison's projected Rating — 45.5 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.
