LONDON (AFP) - Petr Cech made a Premier League debut to forget for Arsenal as his errors helped West Ham United to record a 2-0 victory at the Emirates Stadium on Sunday.
Cech's arrival from Chelsea has been acclaimed as a signing that could turn Arsenal into title contenders, but he was found wanting as Arsene Wenger's side opened the Premier League season with a home defeat for the second time in three years.
Cech's rash charge allowed Cheikhou Kouyate to head West Ham in front from debutant Dimitri Payet's 43rd-minute free-kick and the Czech international's slowness to get down saw him beaten at his near post from 25 yards by Mauro Zarate shortly before the hour.
West Ham's win echoed Aston Villa's 3-1 success at the Emirates on the first day of the 2013/14 campaign and enabled Slaven Bilic to crown his first league game as manager with a famous victory.
In another Premier League match, Newcastle and Southampton drew 2-2.
