Think them to reach the quarters at 14/5 is a decent bet. They would play the winners of Group E in all likelihood, and even if that turns out to be France, I give them a good chance.
Dzeko at 66/1 each way for top scorer is my main bet I reckon.
It's obviously unlikely (what 66/1 bet is likely?) but if he's going to be on the pitch plenty it's a smashing bet. Because if he's starting, I'd argue the odds should be more like 20/1, 25/1. Obviously stiff competition up top for the Argies. Could easily see him getting 4 or 5, and as cliched as it sounds, it's true that it can simply take one thrashing in the group game to give him a massive chance.
