Argentina's World Cup campaign gets underway in Rio de Janeiro tonight, as they face Bosnia in the opening game of Group F.
Alejandro Sabella's side come into the tournament with high hopes, with many believing that it's their time to shine. It would be all the more incredible if Argentina do end up winning the World Cup, as they will have done it in the back yard of their biggest rivals, Brazil.
There are few questions in the final third, with Argentina possessing the likes of Angel di Maria, Sergio Aguero, Gonzalo Higuain and of course, Lionel Messi, but there are concerns at the other end of the pitch, with a shaky defence susceptible to errors.
The team hoping to capitalise on those errors is Bosnia, who will be competing in their first ever World Cup campaign. Safet Susic can rely on stars such as Miralem Pjanic, Asmir Begovic and Edin Dzeko to try and get out of Group F, which would be a superb achievement in their maiden tournament.
If they are to do it though, then they will surely be looking to take maximum points from fixtures against Nigeria and Iran, with Argentina clear favourites to run out winners at the Maracana tonight.
