KARL Robinson took the blame as Oxford United’s shocking start to the season hit a new low, but insisted he was still the right man for the job.

An eighth defeat in 11 Sky Bet League One games came in agonising fashion, as Dan Potts headed a 98th-minute winner for Luton Town at the Kassam Stadium last night.

United took the lead through Ricky Holmes, but defensive errors – starting with Jamie Hanson losing the ball in midfield – allowed James Collins to equalise.

And after skipper Shandon Baptiste was sent off the home side were on the back foot before losing 2-1 with just seconds remaining.

Robinson, whose side stayed second bottom in the table, was dejected, but claimed he would leave if he felt he could not turn the situation around.

“At no stage have I ever doubted that,” he said. “If I felt it was my fault I would walk away. If I felt I was making silly decisions you’d have to look at that and be quite honest and open about that.

“But it’s human error – whether it be Mous’s (John Mousinho) on Saturday, or Jamie Hanson today. They’re not coached those errors we’re making, but fundamentally you’ve picked them so you have to burden the blame.

“To concede in the 98th minute, it doesn’t get much more difficult than that.

“I’m the one who will get the blame, so I have to accept that, 100 per cent. I don’t shirk responsibility.”

The United head coach, who changed his formation for the game to play two up front, admitted it was difficult to work out what he would do next to get the side out of their rut.

He said: “That’s a question you can answer tomorrow morning.

“Right now you’re looking down a dark tunnel with no light at the end of it. Hopefully the longer the time goes on that light will see through.”

Curtis Nelson, however, was quick to jump to Robinson’s defence, with the centre back feeling the defeat came down to on-field decisions made by the players.

He said: “It’s not his (Robinson’s) fault, he doesn’t play out on the pitch.

“Individually we make mistakes and collectively we make mistakes. We’re very naïve.

“We go 1-0 up and we’ve got to be putting the ball in behind and seeing the game out.

“We need to have a bit more game knowhow and that doesn’t come from the manager. We can’t point fingers at the manager, we have that between your ears.

“It’s something we have to learn, quickly.”
