But the former Germany striker remained upbeat after the game. “I’m very proud of our team,” he said. “"Every player on the field made their country proud with this performance in this World Cup."
The game finished 0:0 after 90 minutes and despite Belgium creating the better chances the USA should have scored in the dying moments of full-time.
But at the start of extra-time Kevin de Bruyne scored and Romelu Lukaku then made it 2:0 for Belgium.
But Klinsmann’s men replied minutes later through Julian Green, setting up a nervous finish for Belgium.
Goalkeeper Tim Howard was once again the USA’s man of the match, stopping everything that came his way for more than 90 minutes.
"All of the players went beyond their capabilities and I told them they should take a lot of very positive stuff back home with them," Klinsmann said. "We are doing everything we can in every corner of the country to find the talent."
