Leo Castledine is a 20-year-old attacking midfielder at Middlesbrough, rated 63.9 overall by Field Insider's model. A young player, he has been a fringe squad member this season (14.4% of available minutes). He brings 0.28 goal contributions per 90 (0.28 goals, 0 assists). Below: strengths, watch-points, market-value outlook and the latest transfer news on Castledine.
On the season, Castledine graded 6 for current form (age-blind), on 1 goal and 0 assists in 11 appearances (0.279 involvements per 90).
Year-on-year, that's a drop on last season (Season 12 → 6).
On long-term talent our Rating reads 64. At 20 Castledine is still climbing toward his ceiling, and a market index of 69.5 reflects that trajectory.
Read the appearance count in context: Castledine missed 5 games through injury (inactive, injury) out of roughly 49 this season. The 11 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
A career still climbing — Castledine is at his peak right now, and the curve hasn't flattened.
1 goal in 11 appearances (0.09 per game) — light end product the role wants to see climb.
Rated 63.9 overall — a strong, regular top-tier starter. In the final third he profiles as a work-in-progress on end product (0.28 goal contributions per 90). At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow. With this floor already at 20, the ceiling gets tested by a step up in level — one to track.

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 (~82), then tapers with age. At 20, Castledine sits on 69.5, still climbing toward its peak. The blue line is Castledine's projected Rating — 63.9 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.
