The league’s authorities still plan for all 10 La Liga fixtures to take place, including Barcelona’s match at home to Real Betis tomorrow.
All games across the top two divisions will be preceded by a minute’s silence.
“LaLiga has asked the RFEF (Spanish Football Federation) to hold a minute’s silence in all matches of the first day of the competition in LaLiga Santander and LaLiga 1l2l3,” La Liga said in a statement.
Barca’s players held a minute’s silence before training yesterday, whilst the club published a picture of the players and coaching staff with the hashtag “TotsSomBarcelona” (“We are all Barcelona”) on its social media channels.
“As a mark of respect, the flags will fly at half-mast at the club’s facilities and the players from both teams will wear black armbands in all the club’s matches this weekend,” Barca added in a statement.
“With our hearts still shrinking to see Barcelona, our beloved Barcelona, attacked vilely by terror and hate, we want to show our solidarity with all the people affected as well as to thank enormously all the support received by both the city and our club,” Espanyol said in a statement.
The league’s biggest stars Lionel Messi and Cristiano Ronaldo were among those to lead tributes to the victims as the shocking events of Friday unfolded.
“I want to send my condolences and all my support to the families and friends of the victims of the terrible attack in our beloved Barcelona, in addition to totally rejecting any act of violence,” Barca forward Messi, wrote on Instagram.
“We are not going to give up, there are many more of us who want to live in a world in peace, without hate and where respect and tolerance are the basis of coexistence.”
Ronaldo and his Real Madrid teammates also showed their solidarity with Barcelona as the two clubs’ fierce rivalry was forgotten at a tragic time.
“Dismayed at the news coming from Barcelona. All the support and solidarity (to) the family and friends of the victims,” Ronaldo wrote on Twitter.
That mood was reflected on the front pages of Spain’s sport newspapers yesterday.
“Today we can’t talk about sport,” splashed Madrid-based Marca.
Taking a line from Barca’s club anthem, Barcelona-based Sport’s headline ran “Tots units fem força” (together we are stronger).
The first league matches of the season take place on Friday night when Leganes welcome Alaves in Madrid before Valencia host Las Palmas.
Newly-promoted Girona host Atletico Madrid in the first game in Catalonia since the attacks, just over 50 miles north-east of Barcelona today.
“The most important thing is what happened yesterday,” Atletico coach Diego Simeone said on Friday.
“Unfortunately it was a very hard day for everyone.
“I express my solidarity, sadness and encourage all those that want to live in peace.”
Meanwhile, Barcelona great Pep Guardiola says the people of the city will “stand up” after the terror attacks that left 14 people dead and over 100 injured.
“I am sure the city and country will stand up and move on,” the Manchester City manager told a press conference on Friday. “I just wish it doesn’t happen again in Barcelona or in the whole world.”
A van driver deliberately drove into people on the famous Las Ramblas boulevard on Thursday, creating a scene of carnage, and there was a separate attack in the nearby town of Cambrils.
Spanish police have arrested four suspects and killed five “suspected terrorists”.
Guardiola was born in Catalonia and is one of FC Barcelona’s most emblematic figures, having won 16 trophies there as a player and 14 as a coach.
“Well obviously I am affected by what happened,” said the 46-year-old. “So my best message is for the families and victims.
“Obviously La Ramblas is an important place in the history of Barcelona. Of course the thoughts are for the people who died in difficult conditions.
“It happened in France, in London and unfortunately it happened in Barcelona.
“We don’t know, but Barcelona, we wake up and we show them what a beautiful country it is. Catalonia and Spain, all the best for the future.”
