KARL Robinson was critical of Oxford United's sloppy performance as they slipped back into the relegation zone with a home defeat to Peterborough United.

Ivan Toney settled a game low on quality, when he was found unmarked to fire in from Marcus Maddison's 76th-minute free-kick.

United, who fell back into Sky Bet League One's bottom four as a result, were a shadow of the side who had taken points off Portsmouth, Barnsley and Sunderland in their previous three games.

An unhappy Robinson, who nonetheless felt United were the better side, said: "I didn’t feel at any stage did they (Peterborough) have any dominance in the game, aside from the first five minutes.

"We had the most territorial possession, but it’s a waste of time even saying that because I don’t think we had a cutting edge. I was furious at half-time, I was livid.

"We were getting throw-ins and ambling to them. Who do we think we are?

"There’s an intensity you must have week-in, week-out to perform as a professional footballer, and I don’t see that from my team.

"The whole thing was flat. The performance did not get the fans off their feet, the performance did not keep the fans behind them.

"You can’t come here and say ‘it was quiet’, well you’ve got a responsibility to the fans to perform.

"Win tackles, be aggressive, play forwards, get it your wingers and get your crosses in.

"Everything we worked on we went against at certain stages today."

On an afternoon where United lacked a creative spark going forward, their best hopes came from penalty claims.

Robinson said: "Let’s not forget there’s three blatant penalties – on Gavin Whyte, Marcus Browne and Jerome Sinclair.

"But you can’t blame the referee for his attention to detail when your own house is not in order."

Goalkeeper Simon Eastwood was similarly critical of the home side's display.

He said: "There wasn’t too much in the game, but it didn’t really look like a side that is in a relegation battle.

"We said at half-time we need to up it and almost create our own atmosphere to get the boys going, but we just couldn’t do that."
