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

Alfonso Pérez Burrull refereed 22 Liga matches in which Guti took part, from 2000-01 to 2009-10: 1,418 minutes played, 5 yellow cards and 1 red cards. With the other referees, over the same seasons (266 matches, 15,978 minutes), Guti receives 0.38 yellow cards per 90 minutes, against 0.32 with Alfonso Pérez Burrull.

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".
