Beware an unfancied German team. Jogi Löw's men were supposed to be short of goals, with Miroslav Klose their only recognised striker and Marco Reus absent through injury. Their team spirit was supposed to be shot thanks to rivalry between Dortmund and Munich players. Their defence was supposed to lack proper full-backs.All of that might prove to be true as the tournament progresses, but none of it was a problem as they cruised imperiously past Portugal, with Thomas Mueller scoring a hat-trick in an embarrassing 4-0 pile-on. Brazil, Argentina and Holland, look out.On paper, this is an easy three points for the Germans. If Ghana are as frustrating a proposition as they were in their 1-2 loss to the USA, they have no chance. Endless good possession on the flanks counted for nothing in that game, especially on the right, where Christian Atsu and Daniel Opare both had shockers. Generally they fulfilled the unpleasant stereotype of African teams as hot-headed bottlers wasting their talent.Ghana also won't be able to do much counter-attacking here, which is their strength. They do, however, have one large advantage: the kick-off's at 4pm local time in Fortaleza, where it's going to be somewhere around 30C and muggy with it. Yesterday, Italy showed us what can happen to a good team in the heat. Germany, however, should be better.
