After Celta Vigo striker Iago Aspas cancelled out Karim Benzema's early penalty on Saturday evening, goals from Luka Modric, Vinicius Jr and Federico Valverde kept Real Madrid rolling early in its title defence.
The result on Saturday night strengthens Barca's second place in La Liga, while doing Atletico Madrid a favour in their efforts to qualify for next season's Champions League, as it leaves them three points clear of Betis ahead of Sunday's Madrid derby.
Valencia who was hoping to add to its collection of eight cups, couldn't come out as winners even after scoring four spot kicks taken by Carlos Soler, Uros Racic, Goncalo Guedes and José Gayà.
The 37-year-old has signed a one-year contract at Betis with an option for another year included in the deal. The Chilean has become the second signing of the club for the 2020/2021 LaLiga season.
Betis failed to produce much of a response, despite using all five substitutes and Sevilla strengthened their place in third in the table.
Ousmane Dembele was the latest to join the injured list with a left hamstring strain that will keep him on the sidelines for five weeks.
The transfer deal includes add on worth €12 million and a release clause worth €200 million. It is to be noted that Firpo has signed the contract for five years.
Supporters chanted the goalkeeper's name at Madrid's home pitch Santiago Bernabeu and gave Navas a standing ovation during what could be his last game with the Spanish side, while he knelt prayer-like and pointed to the sky late on Sunday.
Barcelona, although it controlled the ball just 44 per cent of the time, a record low in league games since the 2004-2005 season, still managed to implement coach Ernesto Valverde's plan switching from a 4-3-3 configuration to 4-4-2, dropping Philippe Coutinho for Arturo Vidal.
Real Betis prevailed over Girona 3-2 thanks to a last gasp penalty successfully converted by midfielder Sergio Canales, to earn their first La Liga win in four matches on Sunday.
