Player data: 2000-01 → 2021-22 only. Player-level match sheets come from Zenodo (BeSoccer, CC BY-NC 4.0 licence, non-commercial use). No free source provides them after 2021-22: more recent matches are not counted here. Penalties conceded are not attributed to players in the source, so they are not analysed.

In short

Pérez Lasa refereed 22 Liga matches in which Andrés Iniesta took part, from 2004-05 to 2012-13: 1,449 minutes played, 4 yellow cards and 0 red cards.
