It wouldn't be a World Cup without a shock or two. Can any of the below wagers land you a winner?
Serbia to reach the quarter-finals
You'll know all about Branislav Ivanovic and Nemanja Matic, but some of their Serbian team-mates could become household names too this summer. Look out for midfielder Sergej Milinkovic-Savic and winger Andrija Zivkovic. Serbia are in a tough group but face tournament favourites Brazil in game three, so if they do well against Costa Rica then Switzerland, the pressure might be off. If they finish as runners-up, they'll play the winner of Group A, which we reckon might be Uruguay or Egypt (see below). We'll back Serbia at 7.8 to reach the last eight.
And Mexico could get there too...
In qualifying for their seventh-successive finals, Mexico played excellent attacking football and lost only one match (a post-qualification dead rubber). Like Serbia, their squad is a mix of experience and exciting youngsters, in particular 22-year-old striker Hirving Lozano who's been attracting Premier League club interest following a brilliant season for PSV Eindhoven. Mexico face holders Germany in their opening match but things get easier when they face a weak-looking Sweden and South Korea. Unlucky to lose 2-1 to Holland in the round of 16 in 2014, Mexico have reached two quarter-finals and, at 7.0, they could be worth backing for a third.
At bigger odds than 30/1 on the Exchange, the experienced Uruguay offer plenty of back-to-lay value in the outright winner market. In Diego Godin and Jose Gimenez, the South Americans have two centre-backs that ply their trade in one of the meanest defences in Europe in the form of Atletico Madrid. In attack, Edinson Cavani and Luis Suarez scored a combined 53 league goals last season, while Maxi Gomez and Cristhian Stuani both impressed in Spain's top tier for Celta Vigo and Girona, respectively. Oscar Tabarez's men are strong favourites to top the group and are seeded to face a relatively limited Portgual in the last 16, so have every chance of making the quarters. At this point, a profitable Cash Out should be on the table.
