The defender admits it was a hugely disappointing match for England in Copenhagen as the Three Lions slipped to a 4-1 reverse.

But he insists the squad will now focus totally on the crucial World Cup qualifier against Wales in Cardiff on 3 September and will not let their fans down again.

"It was obviously a very bad defeat and we have to be honest about that," he said.

"We can’t make excuses and the only thing we can do now is concentrate 100 per cent on beating Wales, because that after all is the match that really matters.

"It would be a disaster if England didn’t qualify for the World Cup and this must be a wake up call.

"I don’t believe our confidence will have been knocked hard, because we are a strong group of players and we will come back in two weeks time against Wales. We have to."

Neville believes the first-half performance against Denmark wasn’t bad, but England lost shape after the break and he admits there were not too many positives.

He said: "It wasn’t a performance we can be proud of, it was very disappointing. But the main problem was that we let it slip in the second half because in the first half we did well and should have been two goals up.

"A few players did themselves justice first half because we created chances against a good side. But we win as a group and we lose as a group and overall it was very bad. We have to forget it and think about beating Wales."
