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

Hernández Hernández refereed 21 Liga matches in which Toni Kroos took part, from 2014-15 to 2021-22: 1,783 minutes played, 3 yellow cards and 0 red cards.
