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

González González refereed 21 Liga matches in which Sergio Ramos took part, from 2010-11 to 2019-20: 1,832 minutes played, 7 yellow cards and 1 red cards. With the other referees, over the same seasons (269 matches, 23,422 minutes), Sergio Ramos receives 0.34 yellow cards per 90 minutes, against 0.34 with González 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".
