Manager John Sheridan blasted the sloppiness of his Plymouth Argyle side after their 1-0 defeat by Oxford United at Home Park on Saturday.
Sheridan was at a loss to explain why the Pilgrims put in such a dreadful display, especially before half-time.
Oxford had picked up only one point out of a possible 15 before their visit to Home Park but could – and should – have won by a much wider margin.
Argyle had been unbeaten in Sheridan's first four matches as manager and were coming off a 2-1 win away to Aldershot Town the previous Saturday. But their play lacked any confidence or fluency as, for the third successive npower League Two home game, they failed to score a goal.
Sheridan said: "You wouldn't think we were a team unbeaten in four and after a really good result last week.
"We came into a home game against a team who haven't won in five and you would think we would be the confident ones going out on the pitch. I'm very disappointed, especially with the first half performance. We looked frightened. I don't know why.
"There wasn't any energy. There was a great opportunity to push away from one or two teams near the bottom.
"We just didn't get going. That should never be the case. It was probably the sloppiest we've been. We were sloppy all over the place and I hate that. I have a big downer on people who are sloppy. They get paid good money and should be able to go out and perform a lot better than they did."
Sheridan used only one of his substitutes, with Gozie Ugwu – in his first start for Argyle – replaced by Ronan Murray in the 70th minute. However, the Pilgrims' boss threatened to shake up the side for the visit to Northampton Town this coming Saturday.
Sheridan said: "I'll have to look at it. There are one or two players who want to be in the team and think they should be in the team, so I might make changes.
"Some of the decisions we made were criminal," added a perplexed Sheridan.
The only goal of the game came in the 16th minute when striker James Constable was not picked up inside the penalty area and slotted home from close range.
Sheridan said: "Oxford have some good players. I think they are one of the better teams in the division. I knew what to expect but we were the home team and there was no urgency to us. I can't answer why it was because we are unbeaten in four, we got a great result last week, and you would think we would be buzzing.
"There was a lot of talking before the game from the players, but none of them were talking once they went out on the pitch. I'm frustrated and disappointed with the way we played. It's not right and it shouldn't happen."
Sheridan did not see any point in 'ranting and raving' at the Argyle players immediately after the game. He said: "I don't think it's a time now for me to be in there and giving them rollickings. I would love to, though, because I think the performance merited it. I want one or two players to look at their performances.
"People always say that my teams play football but we haven't played much football since I've been here. We've just got to try to get some confidence.
"At home, we don't get going and I don't know why. The crowd do get behind us, but we're not giving them much to cheer about at home."
Sheridan added: "I've got to look at it. If I have to make changes, I'll make changes.
"I've got players who I think can play football. They've looked all right in training. I'm not a lover of changing my side, but after that performance I might just throw one or two in.
"I don't mind losing football matches. I expect us to lose football matches, but not in that manner."
