The balance wasn't right at all though.
Yeah I don't argue that they played better once Klose came into the team but the original question was whether they struggled to score, they didn't. As you say they were poor in certain games including the one against Ghana yet they still managed to score twice.The balance wasn't right at all though.
Portugal self destructed in the first game and Germany were poor against Ghana, USA and Algeria but got away with it. It's only when Löw finally switched Lahm back to right back and brought Klose in up front ahead of the France game that the team started looking like genuine contenders.
He's doing the same thing again, playing players out of position this time. Hopefully he's grasped the fact it's not working a bit earlier this time round, today was a positive step.
