Russia could be embarassed in two years when they host World Cup, even in a light group. They basically must beat Wales to have any chance of third place. Good win for Slovakia but due to H2H tie breaks they will probably finish 3rd unless to get something from England
Dzagoev changes them drastically. If they trust Neustadter in the heart of their defense (alongside Fernandes), and a kid like Miranchuk establishes himself; they could actually be interesting. But Slutsky certainly has a lot of work to do rebuilding the mess that Capello left him; and they'll need good fortune with fitness n form with their key players.
If things do break their way tho, and Slutsky can establish a similarly smooth attacking structure as he did with ZSKA, they could actually make some waves as they did in 2008...at least until they get cocky & choke. I'd be interested to see something like this:
Dzyuba/Smolov/Kokorin - Cheryshev
Miranchuk
Shennikov - Shatov - Dzagoev - Smolnikov
Neustadter - Novoseltsev/Chernov/Lystsov - Fernandes
Akinfeev
