Reading 1-0 West Ham: Huge errors cost Hammers - Sam Allardyce

West Ham manager Sam Allardyce says his side suffered from two "huge mistakes" that led to a 1-0 defeat by Premier League strugglers Reading.

Central defender James Collins's back pass was seized upon by Pavel Pogrebniak to score the only goal of the game in the first-half.

Allardyce feels that error should have been cancelled out when Ricardo Vaz Te found himself unmarked a few yards out only to head a chance wide that "couldn't have been any easier to score."
