Northern Ireland have qualified for the European Championship for the first time thanks to a 3-1 defeat of Greece on Thursday, but it is still all to play for in Group D as Germany, Republic of Ireland and Poland all remain in the hunt going into the final round of fixtures.
Qualification for next year's competition ends a 30-year major-tournament drought for Northern Ireland and victory never appeared in doubt on Thursday, with Steven Davis at the double.

Davis' second just before the hour-mark put the game beyond Greece despite Christos Aravidis' late consolation, securing Northern Ireland a first appearance at a major tournament since the 1986 World Cup.
Joining Northern Ireland in clinching qualification were Portugal, who beat Denmark 1-0 thanks to Joao Moutinho's second-half winner.
Nani had gone closest for the hosts when he hit the crossbar with a header, but Denmark were not let off by Moutinho who produced a fine finish after a display of quick feet on the edge of the area.
