Real Madrid beat Eibar 3-1 in their first competitive match at the Alfredo di Stefano stadium following La Liga's three-month break due to the Covid-19 pandemic.
Toni Kroos got Real off to an ideal start at the empty stadium based at their training ground by scoring in the fourth minute while captain Sergio Ramos struck on the half-hour mark before Marcelo netted in the 37th.
Real did ease off after the interval and Eibar forward Sergi Enrich struck the woodwork before Pedro Bigas pulled a goal back for the visiting side on the hour mark.
Real coach Zidane used all five of his substitutions as his players continued to tire.
The win kept Real on La Liga leaders Barcelona's heels with 59 points after 28 games. They are two points behind Barca after the Catalans beat Real Mallorca 4-0 on Saturday.
Diego Costa paid tribute to Atletico Madrid women's star Virginia Torrecilla in Atletico's 1-1 draw at Athletic Bilbao.
The striker scored his first goal of the year and celebrated with Torrecilla's shirt after the midfielder had successful surgery for a brain tumour in May.
The draw saw Atletico, who are sixth, miss the chance to move into LaLiga's top four after they came from behind on Sunday.
Bilbao captain Iker Muniain opened the scoring eight minutes before the break when he steered in Yuri Berchiche's cross with the outside of his foot.
Costa levelled two minutes later when he latched onto Koke's through-ball and prodded in his first goal since October.
Champions League hopefuls Real Sociedad were held to a 1-1 home draw by Osasuna.
Sociedad's Mikel Oyarzabal cancelled out Adrian Lopez's first-half penalty for the visitors to leave them fourth on 47 points from 28 games, one point ahead of fifth-placed Getafe who are chasing the last qualifying spot for next season's Champions League.
Getafe slumped to a 2-1 defeat at Granada on Friday, but Real failed to make the most of that slipup as they seemed to lack inspiration without fans creating an atmosphere, with all matches being played behind closed doors.
The result left Osasuna in 11th place on 35 points.
