whilst the Croatia v Spain match remained at 0-0 and Italy led 1-0. Three teams were tied on 5 points. In the matches between the three teams concerned (ie ignore Republic of Ireland games)
Italy P2 W0 D2 L0 F2 A2 GD 0
Spain P2 W0 D2 L0 F1 A 1 GD 0
Croatia P2 W0 D2 L0 F1 A1 GD 0
so Italy led this mini-group by virtue of scoring one more goal at that stage but Spain's goal changed this.
