The Reds hit the woodwork three times against Stoke, but it was the outside of the upright each time rather than a close call, and they were chances squandered rather than a case of bad luck.
"There was a bit of frustration in the dressing room after the Stoke game," Cole told liverpoolfc.com.
"We felt we should have won the game with the chances we had.
"The only criticism of us that I would have was that we didn't stick the ball in the back of the net. We just lacked that final bit. We have two weeks now to work on it and we're looking forward."
