BARCELONA — Barcelona's 16-year-old forward Ansu Fati continued his explosive start to life in the first team by scoring and providing an assist as the La Liga champions thrashed Valencia 5-2 on Saturday.

Goals from Fati, Frenkie de Jong, Gerard Pique and two from Luis Suarez gave Barca their second win of the season.

Kevin Gameiro and Maxi Gomez scored for Valencia, who suffered their biggest defeat in over three years in coach Albert Celades' first game.

The victory took Barca on to seven points after four games, while Valencia have four.

Fati, who became Barca's youngest ever goalscorer two weeks ago by netting at Osasuna, struck his first goal at the Camp Nou to give Barca the lead with less than two minutes on the clock by smashing a pass from De Jong into the net.

The goal had the injured Lionel Messi grinning in admiration as he watched on from the stands but the teenager had fans on their feet again five minutes later as he dashed into the area and teed up De Jong to score his first goal for the club.

Valencia were playing their first game since owner Peter Lim took the surprise decision to sack Marcelino, the coach who had secured Champions League football twice and also led the team to victory over Barca in last year's Copa del Rey final.

They pulled a goal back later in the half through Kevin Gameiro but Barca came flying back at them after the interval.

Pique bundled the ball into the net in the 51st minute after Antoine Griezmann had hit the post while Luis Suarez netted twice after coming off the bench.

Making his return after getting injured on the first day of the season, Suarez flummoxed Valencia goalkeeper and former team mate Jasper Cillessen with two thumping finishes, one which went in off the near post, the other settling in the near corner.

Suarez was given a warm reception by Barca fans but it was nothing compared to the remarkable standing ovation they gave to Fati, who heard his name chanted by supporters when he came off to make way for the Uruguayan.

"He (Fati) is delighting the fans and making them very excited," said Sergio Busquets of the teenage sensation.

"Every time a player like him bursts on to the scene he is compared to many players but we need to support him and let him continue to grow. He still needs to be aware of where he is and how difficult it is to make it."

Maxi Gomez got a consolation goal in stoppage time for Valencia, who fell to their heaviest defeat since they were thumped 7-0 at the Camp Nou in 2016 when Gary Neville was in charge.

"We cannot forget what has happened in the last few days and how traumatic it has been for some," said beaten coach Celades, who is in his first role as a senior first team coach.

"This scoreline hurts us a lot but we can only look forward and keep working and try to improve." — Reuters
