SPAIN need just a point against Croatia for the sides to qualify first and second from Group D.
The Croats are 4-1 at bet365 to notch the victory that will send them through in top spot.
If the Croats lose to the Spanish they risk being overtaken by the Czech Republic who start as 6-4 favourites with McBookie to beat Turkey.
At Euro 2012 Spain won 1-0 and haven't conceded in their last 10 – and in 20 of their previous 22 – but there is a chance of Vicente del Bosque resting some players including Sergio Ramos who is on a booking.
Croatia could be without injured Luka Modric and that's a massive concern for a side who rely so much on the Real Madrid playmaker.
It's one of those games where you want to see teams before having a bet but under 2.5 goals tempts at 5-7 with 888sport.
Czech Republic looked on their way out when they trailed Croatia 2-0 but hit back to level with an injury-time penalty in a match ruined by fan trouble.
The result will have lifted the Czechs who must go out and beat their rivals and hope it's good enough for a best third-placed spot unless Croatia crash. They are 6-4 at McBookie.
Turkey were well beaten in their first two games and haven't kept a clean sheet at the Euros since a 2-0 win over Belgium at Euro 2000. They've conceded 15 goals in eight games and I don't see them getting anything from a side who topped their table in qualifying.
But of course it may end up meaning nothing and that's the problem with these two games.
Bets to Consider
