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

Martínez Munuera refereed 20 Liga matches in which Isco took part, from 2013-14 to 2021-22: 1,040 minutes played, 3 yellow cards and 0 red cards. With the other referees, over the same seasons (226 matches, 12,131 minutes), Isco receives 0.13 yellow cards per 90 minutes, against 0.26 with Martínez Munuera.

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".
