England flanker Tom Wood apologised to their rugby public after the host nation were knocked out of the World Cup following defeat to Australia on Saturday.
The loss leaves England with two defeats from three games before facing Uruguay, with Stuart Lancaster's men coming off distinctly second best at Twickenham.
Australia scored three tries in the one-sided game in what was a dominant showing that left Wood honest in his assessment.
"A bad day, a real bad day and I can't explain how much it hurts or articulate what went wrong. You have to give credit to Australia – they were sharp when they needed to be and we didn't have answers. I apologise that we didn't have enough," he reflected.
"Australia cut us when it mattered – they were razor-sharp when they needed to be. We have some strong characters who will be hurting like hell now, but they will get back to it."
The 33-13 loss follows a 28-25 defeat to Wales and Wood could not hide his disappointment at their recent form on home soil.
"Last week we let Wales of the hook, but today we were comprehensively beaten. It's unbelievably hard that it's come to this – we have left no stone unturned in terms of mental preparation and physical prep. It's just not happened," he said.
"We could have played brilliantly well and lost to a very good Australian side. I would like to say we were in a fight to the death at the end, but we were clutching at straws.
"We are out of the World Cup. It's our World Cup and we have not delivered anything like what we thought we could. We felt we were genuine contenders to win it."
He added: "We knew the pressure was going to be there whether it was this week, next week, a quarter-final or semi-final. The group was always going to be incredibly tough, but we were so confident and I don't think there's anything we would do different in our preparation, but unfortunately it wasn't enough."
