Barcelona keeps winning in Spain

Barcelona won its fourth game in a row at the start of the Spanish league and is the only team with a perfect record after four rounds.

Yamal scored a goal in each half following his first two goals of the season in the win against Rayo Vallecano in the previous round.

"I think we played a fantastic game," Barcelona coach Hansi Flick said. "We controlled the game, we were dominant. This is what I want to see from the team."

Fermín López, Raphinha and Pedri also found the net for Barcelona, which has outscored opponents 17-2 in four games. López was man of the match after also helping to set up two of the goals.

Midfielder Rodri made his first start since joining Barcelona from Manchester City, and newly signed forward Gabriel Jesus came off the bench in the second half for his Barcelona debut.

Defender Eric García had to be replaced in the first half after being struck in the face in a collision with Rodri.

Valencia lost its third in a row. It has scored only once in four matches. The home rout sparked protests against the team owner and players by Valencia fans, who gathered in large numbers outside the Mestalla Stadium after the match.

Lucas Boyé had a hat trick and Mariano Díaz scored his third goal of the season as Alaves defeated Osasuna 5-2 at home for its third win and second place in the standings.

Sevilla, with 10 men from the 56th, took the lead at Espanyol in the 85th but conceded deep into stoppage time for a 1-1 draw.

Reyna scores first goal with Strasbourg in France

Reyna got his first goal with Strasbourg in his new club's trouncing of promoted Troyes.

The 23-year-old U.S. international joined Strasbourg from Borussia Monchengladbach.

Augsburg's second straight win saw the club go top of the standings on goal difference. Three other teams have also won two matches to start the season - Freiburg, Borussia Dortmund and Elversberg.

Goalkeeper Koeman Jr. scores twice

Telstar goalkeeper Ronald Koeman Jr., son of former Dutch star Ronald Koeman, scored twice from the penalty spot to help his team salvage a 2-2 home draw against Cambuur in the Dutch league.

The 31-year-old Koeman Jr. had already attracted attention last season after converting a late penalty that helped the club avoid a relegation playoff.
