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 20 Liga matches in which Pepe took part, from 2008-09 to 2016-17: 1,800 minutes played, 6 yellow cards and 0 red cards. With the other referees, over the same seasons (189 matches, 16,260 minutes), Pepe receives 0.24 yellow cards per 90 minutes, against 0.30 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".
