MADRID, Sept. 1 (Xinhua) -- Gareth Bale and Karim Benzema were again decisive as Real Madrid prolonged their 100 percent start to the season with a 4-1 win at home over Leganes.

The pair, who were underdogs when Cristiano Ronaldo was at the club, once again came up with the goods to help forget the Portuguese forward who joined Juventus in July.

Thibaut Courtois made his debut for Madrid and his side took the lead in the 17th minute thanks to Gareth Bale.

Leganes equalized seven minutes later after Casemiro fouled Javi Erraso and Carrillo scored from the penalty spot.

The 1-1 continued until the second half when Madrid improved drastically and two goals from Benzema, his 3rd and 4th of the season, put the result before doubt, before Unai Bustinza's foul on Marco Asensio allowed Sergio Ramos to score his side's 4th goal of the game.

Atletico Madrid's irregular start to the season continued with a 2-1 defeat away to Celta Vigo.

Diego Simeone's side were again a long way from their best form and fell behind to a goal from Maxi Gomez less than a minute into the second half. Iago Aspes doubled Celta's lead six minutes later and Atletico's evening was complete when Stefan Savic was sent off for a second yellow card 20 minutes from time.

Friday kicked off with a dull 0-0 draw between Getafe and Valladolid. While Girona won 1-0 away to Villarreal thanks to a Christian Stuani goal.

Finally Eibar scored their first goals of the season as they claimed their first points with a 2-1 win at home to Real Sociedad.

Willian Jose put Real Sociedad ahead from the penalty spot, although he had to leave the game with a muscle strain directly afterwards, but new signing Marc Cardona equalized shortly afterwards and Charles gave Eibar all three points with a goal in injury time.
