David Moyes rued West ham United's wastefulness against Brentford on Sunday.
The Hammers were ultimately punished at home when Yoanne Wissa scored in the 94th minute to claim a 2-1 win for Brentford.
"I don't know how many times we got into the byline and didn't pick out the pass and take the chance," Moyes said.
"We really today didn't take the opportunities we had and we had quite a few.
"I thought today we did create them but we missed other really good opportunities to create really good chances. Today wasn't for a lack of chances.
"We had the chances to score the second goal just didn't take it."
