A shellshocked Oscar lies on the pitch after their 7-1 defeat to Germany

Coach Luiz Felipe Scolari says Brazil’s “catastrophic” 7-1 defeat to Germany in the World Cup semi-final was “the worst day of my life.”

The hosts’ dream of reaching the final on home soil was blown away in a scarcely believable first half, which shellshocked Brazil finished 5-0 down - all five goals coming in just 19 minutes.

Calamitous defending, and some superb German attacking play combined to produce a scoreline which sent shockwaves through Brazil and the rest of the footballing world.

Thomas Muller got the Germans up and running in the eleventh minute, but the game was lost in seven astonishing minutes. Miroslav Klose scored on 23, Toni Kroos added two more on 24 and 26 and Sami Khadira scored the fifth on 29. Andre Schurrle both scored twice after the break before Oscar pulled one back in the last minute.

Scolari admitted: “Today was the worse day of my life - but life goes on. My message for the Brazilian people and fans is that we tried to do what we could do, our best, versus a great team.

“They finished off the match in three or four minutes with some fantastic goals. The atmosphere in the changing room was terrible obviously. But we are going to continue working hard to keep improving.

"I'm sorry we could not reach our goal. The fans supported us even when it was five, six, or seven down to Germany.

"I am responsible for this catastrophic result. I made the choices. I was responsible. We ask for forgiveness. To the people, please excuse us for this negative mistake.”

Scolari insists the nature of the match and the gulf between the teams on the night does not mean Brazil are being left behind by other footballing powers.

"I don't agree that we're behind from a strategic standpoint. This was my third loss. But this was the worst loss,” he said.

"Should we have to reinvent our team after one game? Half this team will play at WC 2018. At least 13, 14, 15 of them will be in 2018.

"What happened today had little to do with how we had been playing. We lost control... that's not normal but it happens.

"It was one goal after the other. It was like we blanked out. We tried to talk to them, to organise them. There was nothing we could do.

"A coach makes choices and has to deal with consequences. I don't have any regrets for the choices I made. Trying to turn around a 5-0 after the first half is impossible."

"They (the Germans) negatively influenced my team. We have to sit down and analyse things. The German quality wasn't normal. We have to know how to take on this defeat.

"I think they have five or six players with more than 120 caps. They had their best match today. Us? Our worst."

Asked directly if he will resign, Scolari said: "Don't forget there's a match on Saturday, the third place play-off."

Scolari also rejected the suggestion that Neymar's serious injury, and the emotion created by his absence, had played a key part in the defeat.

"No, no, no. Let's not try to find an excuse in Neymar or the emotions of the anthem," he said. “I don't think it would have been different with Neymar. He's a striker.

"Germany probably could have done that with Neymar in the side, also. He wouldn't have known how to defend those moves for the second, third, fourth and fifth goals."
