Angry fans stayed behind long after the final whistle to barrack Oxford United’s manager and players after the U's crashed 2-1 at Hayes & Yeading yesterday.

Faltering United, who have now won just one of their last eight matches, had Matt Green dismissed in the first half and boss Chris Wilder sent from the dug-out at the start of the second half.

Wilder and his coaching staff were furious at the referee’s handling of the game, as Green was sent off for two yellow cards in two minutes while Hayes right back Danny Allen-Page went unpunished for elbowing Simon Clist.

Clist left the pitch with blood streaming from his head and was taken to hospital with concussion.

The U's led 1-0 at half-time through James Constable’s 20th goal of the season, but Hayes hit back with two goals in the second half to complete the double.

Some United supporters stayed behind for a long time and one was very vocal in his criticism, shouting at the players “Why don’t you show the same passion as I am.”

Wilder’s assistant, Mickey Lewis, did the post-match press conference, because Wilder, having been ordered to the dressing room area, did not see much of the second half.

“He wasn’t actually sent off, there wasn’t a red card or anything, he was just asked by the referee not to watch the second half,” Lewis said.

“There were a few contentious decisions, but Chris hasn’t shouted at the referee or anything, he just went to ask him about the challenge on Clist, where the lad’s got concussion and there’s blood everywhere, why their lad wasn't even booked.

“Matt Green's first booking too we felt was a little bit soft. We were disappointed with the referee’s performance. The second one probably was a booking.

“I thought in the first half we played well.

“At half-time the manager’s said several things and the lads have really killed themselves by conceding a sloppy goal in the first minute.

“It’s really frustrating as a management team when the information you give is not taken and acted upon.

“Damian Batt should have knocked it down the line in the first minute of the second half, then the ball comes into the box and we didn’t deal with that.

“From looking the better team, that gave Hayes & Yeading the impetus.

The whole game changed, one or two of our lads looked a bit tired, especially after Tuesday night on a heavy pitch – and Hayes hadn’t played in midweek.

“But still Sam Deering could have scored. We’ve got to take those chances.”
