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 28 Liga matches in which Gerard Piqué took part, from 2006-07 to 2018-19: 2,476 minutes played, 7 yellow cards and 1 red cards.
