Hamburg: Thomas Mueller netted twice as Germany eased to an impressive 3-0 home win over the Czech Republic to keep them top of their World Cup qualifying group on Saturday. It leaves Germany with a perfect six points ahead of Tuesday's next qualifier, home to Northern Ireland, who beat San Marino 4-0 in Belfast. Germany stay top of Group C on goal difference from surprise-package Azerbaijan on the road to Russia 2018.
