Marcelo took advantage of his time off to travel to Valencia with his family, though his actions appear to breach Spain's coronavirus restrictions.
The Brazilian defender uploaded a photograph of himself and his family to social media, showing them sitting at the beach in Valencia.
If this picture was taken this weekend, Marcelo would've been breaking COVID-19 rules in Spain, which state that people should not move between specific regions. Taking a trip from Madrid to Valencia for leisure is not allowed, for example.
During the Christmas holidays, Marcelo also appeared in a photo with his family in a hotel in Sierra Nevada, despite the COVID-19 restrictions on mobility at the time.
Zinedine Zidane has given his players a couple of days off during the international break, with those not off with their countries expected back for training again on Monday.
