West Ham mistakes punished by Arsenal - Sam Allardyce

Manager Sam Allardyce says West Ham were "severely punished" for making too many mistakes in their 3-1 home defeat by Arsenal.

Mohamed Diame had put the home side infront on 21 minutes, but Olivier Giroud, Theo Walcott and a Santi Cazorla wonder strike helped push Arsenal above West Ham in the table and go fifth.

Allardyce admits his side should have taken their chances, including when Kevin Nolan missed two opportunities to put the hosts back infront.
