MADRID, Sept. 15 (Xinhua) -- FC Barcelona's 16-year-old striker Ansu Fati needed just seven minutes to write the headlines of the fourth round of matches in La Liga.
This was the time Fati needed to score his first goal in the Camp Nou and set up Frenkie de Jong for Barca's second goal in a 5-2 thrashing of Valencia.
Valencia, who had replaced coach Marcelino Garcia Toral with Albert Celades three days before the game, got back into the match thanks to Kevin Gameiro, but after Gerard Pique tapped in Barca's third at the start of the second half, it was game over and Luis Suarez came back from injury to score two more goals, before Maxi Gomez's late consolation effort for the visitors.
There were double celebrations in Real Sociedad's Reale Arena as the home side were able to not only inaugurate the remodeled former Anoeta Stadium, but to do so with a 2-0 win over Atletico Madrid.
Martin Odegaard and recent arrival Nacho Monreal scored in the 57th and 60th minutes of the game to end the 100 percent record of a disappointing Atletico.
Real Madrid produced a 'game of two halves' which saw Karim Benzema and Casemiro put them 3-0 at home to Levante in the first 45 minutes before a second half which saw Borja Majoral and Gonzalo Melero bring the visitors to the brink of snatching an unlikely point in a game which saw Eden Hazard saw his long-awaited Real Madrid debut.
Sevilla went to the top of the table thanks to a spectacular 36th minute from midfielder Joan Jordan which gave Julen Lopetegui's side a 1-0 win away to Alaves.
Next week sees Sevilla entertain Real Madrid, who last season sacked Lopetegui before the end of October and Lopetegui has the chance for some early revenge.
Espanyol claimed their first win of the campaign with two goals in three minutes away to Eibar.
The home side had taken the lead through Ivan Ramis and were in total control until the central defender injured his knee and had to leave the pitch, just seconds before Facundo Ferreyra equalized.
The Espanyol striker was injured in scoring the goal, but his substitute Esteban Granero then popped up to score the winning goal after a defensive error.
Celta Vigo paid the price for playing with nine men for over an hour after first Jorge Saenz and then Fran Beltran were both sent off for bad challenges in their home game to Granada.
The visitors took the points thanks to a goal in the sixth minute of first half injury time from German and a 53rd minute strike from Yangel Herrera, who hit a powerful shot from distance into the top corner of the net.
Osasuna remain unbeaten after a 1-1 draw away to Valladolid where Rober Ibanez's 81st minute goal cancelled out Hervias' free kick for the home side.
There were two penalties as Betis drew 1-1 at home to Getafe as Joaquin Sanchez's 73rd minute spotkick cancelled out Jaime Mata's 15th-minute opener for the visitors, who remain winless this season.
Despite dropping two points at home, Betis will be the happier of the two sides after William Carvalho was sent off in the 25th minute.
Leganes remain rock bottom and pointless after a 3-0 home defeat to Villarreal which came partly thanks to two goals from Gerard Moreno.
