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

Undiano Mallenco refereed 21 Liga matches in which Guti took part, from 2000-01 to 2009-10: 1,251 minutes played, 6 yellow cards and 0 red cards. With the other referees, over the same seasons (267 matches, 16,145 minutes), Guti receives 0.37 yellow cards per 90 minutes, against 0.43 with Undiano Mallenco.

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".
