West Ham manager Sam Allardyce says his side made too many big mistakes after losing 3-0 to Chelsea and hopes their next two games will be a turning point for the Hammers.

Frank Lampard scored twice against his former club, with Oscar also on target, as Chelsea moved up to third in the Premier League table.

West Ham not won in the Premier League since beating Spurs in early October.
