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

Iturralde González refereed 20 Liga matches in which Xavi took part, from 2000-01 to 2011-12: 1,704 minutes played, 1 yellow cards and 0 red cards. With the other referees, over the same seasons (350 matches, 28,260 minutes), Xavi receives 0.11 yellow cards per 90 minutes, against 0.05 with Iturralde González.

Verdict: no clear difference with the other referees.

Cards are rare (less than one per player per match): over a few dozen matches, only a very large deviation can be told apart from chance. "No clear difference" does not mean "no effect".
