Loew wary of Greek threat

Germany coach Joachim Loew has warned his players about "champions of efficiency" Greece ahead of their Euro 2012 quarter-final tie.

Loew's side booked their place in the last eight with a 2-1 win over Denmark on Sunday evening and are clear favourites going into the match against Greece. But the coach insists his side still have plenty to do against the 2004 European champions. He said: "The Greeks have had three goals chances thus far in the tournament and scored three goals. They are the champions of efficiency."
