The match ended in a 3-3 draw.
“We showed great morale to come back from every goal they scored,” Löw said.
“But when you draw 3-3, obviously not everything has gone well. We were not so good against their long balls.
“We will try to improve on a few things. We wanted to take three points but I am happy because we had a number of young players on the pitch.”
He added: “Miroslav Klose was a class act tonight. Trust counts for a lot in life.”
