Output in context · FC Porto finished 1st of 18 · a title-challenging side
4.06 tackles, blocks & interceptions per 90 — solid defensive volume, with 15 clean sheets across 26 appearances. Behind a title-challenging side (1st 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. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.

- Defensive volume. 4.06 tackles, blocks & interceptions per 90 — does the unseen work.
