The Republic of Ireland will be hoping to get underway with a win when they take on Croatia in Poznan.
Both sides qualified for the tournament via the play-offs and with similar records during qualification it looks a tough game to call on paper, Croatia won seven of 10 qualification games scoring 18 goals while the Irish won six of 10 scoring 15.
The Republic of Ireland are the 9/4 outsiders, Croatia are 5/4 and the draw is 11/5 but it is a game where both teams will expect to win and want to win to have any chance of progressing given the quality of the other team teams, Spain and Italy, in the group.
Giovanni Trapattoni's men are currently unbeaten in 14-games and have kept 11 clean sheets in this run. A Republic of Ireland clean sheet is available at 21/10, while you can get Ireland to win -1 on the handicap at 7/1.
Croatia will be looking to their creative key, Luka Modric, to unlock the Irish defence and with Eduardo and Nikica Jelavic up-front they should give Trapattoni's team plenty to think about.
Former Arsenal striker, Eduardo, is available at 6/1 to open the scoring with his strike partner 6/4 to score at anything, although with just three goals between them in qualifying it could pay to look further down the list if looking for a goalscorer from the Croatian side.
The Republic of Ireland will likely see this game as their best opportunity to take three points and with a 2-0 win priced at 14/1 it could pay to stick with the Irish for this opener.
