O. Ba is a 30-year-old central defender at Başakşehir, rated 24.4 overall by Field Insider's model, ranking 519th of 720 in the 1. Lig. An experienced operator, he has been a rotation option this season (39.2% of available minutes). His defensive output reads 3.37 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Ba.
Judged on this season alone, Ba graded 23 — a workmanlike campaign that ranks 62nd of 131 of the 131 centre-backs in the 1. Lig, on 5 clean sheets and 3.37 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 25 → 23). Over the 6 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 24, 87th of 131 of the 131 centre-backs in the 1. Lig. At 30 Ba is into the veteran stage, where the age curve weighs on the projection, and a market index of 7.8 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
3.37 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 17 appearances. Behind an upper-table side (5th of 18) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume.
With a Rating of 24.4, Ba carries the 87th-highest potential of the centre-backs in the 1. Lig of 131. Defensively he reads as moderate defensive volume (3.37 tackles, blocks & interceptions 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 (~16), then tapers with age. At 30, Ba sits on 7.8, past its peak and easing. The blue line is Ba's projected Rating — 24.4 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.
