West Ham United boss Sam Allardyce has blamed his side's wastefulness in front of goal for their 1-0 defeat to Tottenham Hotspur in the Premier League.

The Hammers wasted 18 chances at Upton Park on Saturday before Eric Dier scored a late winner for Spurs.

"The length of time it went on, watching the game from sat upstairs or down on the touchline, you know that this game will sometimes bite you when you don't finish off the opposition when you've created so many chances," Allardyce told the club's official website.

"We paid the ultimate price in the last minute because we didn't secure the victory well before Tottenham got their goal. When Tottenham did get their goal, it was with their last chance and probably their only clear-cut chance in the whole game."

West Ham continue their Premier League campaign next Saturday when they make the trip to Crystal Palace.
