Germany 'must improve' to recapture World Cup form

But coach says squad handled pressure in victory over Georgia

Captain Bastian Schweinsteiger says World Cup champion Germany must improve ahead of key matches against Poland, Ireland and Scotland as it bids to qualify for Euro 2016 as the Group D winner.

First-half goals by Marco Reus and Thomas Mueller sealed a 2-0 win in Georgia on Sunday which kept Germany in the hunt for automatic qualification for the finals in France after a stunning loss to Poland and a home draw with Ireland last October.
