Jake Wright: Oxford United skipper takes responsibility for loss
Oxford United skipper Jake Wright admitted he "had a nightmare" in his side's 3-2 defeat by Southend.
The U's twice led the game but errors allowed Southend to hit back, even after they had Gary Deegan sent off.
"The defending was really bad and I was involved in all three goals," Wright told BBC Radio Oxford.
"I've just had a nightmare. I went into the dressing room and owned up to it but I have to put it to bed. It'll be a hard week and we need to put it right."
Wright said Michael Appleton's side, who are 17th in the League Two table and three points above the relegation places, have made a nasty habit of throwing away leads.
"You can't keep throwing winning positions away, and against 10 men - that makes it even harder to take," he added.
"We made some chances, their keeper made some good saves and had one cleared off the line. A few times this season, we've been critical of strikers for not taking chances but this was a case of being just not good enough defensively.
"We've let the lads down and if I was a fan, I'd be negative after that. I don't have any problems with that.
"I don't think the pressure is mounting on the manager. He is picking the right team and we're doing things right but if individuals, like me, make so many individual mistakes, that's not the manager's fault."
