Oxford United boss Michael Appleton was left frustrated by the award of another "horrendous" penalty against his side after a 2-1 defeat by Southend United.
Oxford were left still searching for an away league win after Anthony Wordsworth's spot-kick at Roots Hall.
U's right-back Phil Edwards was adjudged to have handled a Ben Coker cross, but Appleton was less convinced.
"It's hard to get your hands out of the way if the ball's smashed at you from a yard away," he told BBC Radio Oxford.
Appleton admitted to being angry at the manner of his side's defeat following a second penalty conceded in as many games.
Edwards was also penalised for handball in a 1-1 draw at home to Charlton on Saturday.
"That's two times in a row now we've been done by horrendous penalties," he said. "But, it happens and we move on."
Appleton admitted a lack of concentration in the final third was another reason for his side failing to take anything from the trip to Essex.
"We missed chance, after chance, after chance," he added." If you don't take those opportunities, you're going to get hurt.
"If we had as much pride and concentration as we've had in our own box in the attacking box, we would probably have five wins by now."
