Poland -Northern Ireland 1:0

Northern Ireland's first match at a European Championship finals ended in defeat as Arkadiusz Milik gave Poland a 1-0 win in Nice.

Ajax star Milik slotted in after being picked out by Jakub Blaszczykowski early in the second half.

Poland had dominated the first half but were thwarted by some superb defending by Michael O'Neill's men.

Northern Ireland did not manage to get a decent effort on target and must now regroup to play Ukraine on Thursday.
