The Three Lions suffered a 4-1 friendly defeat at the hands of Denmark earlier this month, and the England Head Coach insists it won’t happen again.

"I've seen the Denmark game on a tape and the second half was a disaster," he said. "We were sloppy, lost our shape, were not aggressive and were not at all doing the right things.

"It's very difficult to explain what happened. If it had been a qualification game, we should have been knocked out. But it has never happened in a qualification game and it will not happen again.

"We know that 4,000 or 5,000 fans paid for expensive tickets so I'm very sorry that it happened. But it will not happen for those travelling in Wales or Northern Ireland."

Sven names his squad for the two important World Cup Qualifiers at 7.30pm on Sunday ready for the meet up on Tuesday.

"There won't be a lot of changes in the squad we pick," he revealed.

"Then we have to decide how we will play our 4-4-2; if we want to play it as we did in Copenhagen in the first half or if we want to make it like a diamond.

"It might depend on Steven Gerrard's fitness too. We have to talk to Liverpool and him on Monday and Tuesday to find out if he's going to be fit."

England have four days training together before taking on Wales in part one of the ‘British Derby’ double-header next Saturday and Sven believes the prize on offer will spur his team on.

"I was quite happy with the first half [v Denmark], but myself and my coaching staff have a job to get it right before we play Wales. And we will get it right - I'm sure about that," he said.

"It's a World Cup ticket we are talking about. If the players aren't up for that then something is wrong.

"I'm not saying we will win by playing beautiful football but what happened in Denmark will not happen in Cardiff or Belfast. No chance."
