LONDON (AP) — Arsenal got its challenge for the Premier League off to a comfortable but unconvincing start on Saturday with a 1-0 home win over newly promoted West Brom.

Samir Nasri scored in the fourth minute of his Premier League debut to give Arsenal an early edge over its title rivals, with defending champion Manchester United and last season's runner-up Chelsea not playing until Sunday.

Also Saturday, Liverpool won 1-0 at Sunderland, Tottenham's new-look team lost 2-1 at Middlesbrough, Blackburn won 3-2 at Everton, West Ham beat visiting Wigan 2-1, Hull defeated Fulham 2-1, and Bolton beat Stoke 3-1.
