Germany's players made a half-time dressing room pact not to "humiliate" Brazil ‎during their World Cup mauling.

Defender Mats Hummels ‎revealed he and his teammates spoke in the dressing room in Belo Horizonte after storming into a 5-0 interval lead.

They agreed not to 'show-boat', and, after their historic 7-1 semi-final win, Manchester United target Hummels explained: "We just made it clear that we had to stay focused and not try to humiliate them.

"We said we had to stay serious and concentrate at half-time. That's something you don't have to show on the pitch if you are playing.

"You have to show the opponent respect and it was very important that we did this and didn't try to show some magic or something like this. It was important we played our game for 90 minutes."

Brazil were left completely stunned ‎by Germany's rampant victory but Hummels insists they must repeat their World Cup masterclass if they are to win the final on Sunday.

He added: "‎After our second goal they got confused. They were not organised on the pitch and after that we didn't miss a chance until we scored the fifth goal. This doesn't happen too often. You just have to enjoy it.

"We must keep our feet on the ground, but that's no problem for us. We know how hard it will be on Sunday. It doesn't matter who the opponent is on the day. It will be a hard fight and the only chance we have of winning is if we know that from the start.

"We know we are one of the best teams in the world but you always need a bit of luck and for us it was a good day. We must enjoy what happened, but if we lose the final, this semi-final will not be worth anything.

"The game does not have any impact on the final on because it will be a totally different game. It was nice how it went, but it will be no problem keeping our feet on the ground."

Hummels and his teammates were praised by their former manager Jurgen Klinsmann.

The current USA coach, who scored 38 goals in 80 appearances for Germany as a player and managed them at the 2006 World Cup, urged Joachim Low and his players to go on and win the tournament.

Klinsmann tweeted: “The best German performance ever in a World Cup! Simply fantastic! Now get the Cup JOGI and TEAM!”

And former Germany and Liverpool midfielder Dietmar Hamann was equally impressed, saying: “Master-class from Germany. Clinical, organised, hard-working, unselfish and humble. Very proud of the team. One to go.”
