After a miserable first Premier League outing for Arsenal, goalkeeper Petr Cech has been assessing his performance.
Petr Cech has taken to Twitter to concede his nightmare Arsenal debut against West Ham was "not in the script".
The former Chelsea goalkeeper - tipped to be the difference as Arsenal bids for a first league title in 12 years - was culpable for both goals as his side lost its Premier League opener 2-0.
Cech flapped at a Dimitri Payet free kick to allow Cheikhou Kouyate to head home just before halftime and reacted slowly to a long-range Mauro Zarate strike after the break that doubled West Ham's lead.
