Milinkovic-Savic will be crucial for Serbia. His height advantage over Casemiro can be exploited by Serbia with direct vertical passing from deep, just as Lazio do. His pressing can unsettle the Brazilian defensive midfielder and, if he forces Casemiro into a pass backwards, he needs to follow that up. Brazil’s game plan can be greatly unsettled by targeting the central passing axes of the centre-backs and deep dropping midfielders, and so Mitrovic and Milinkovic-Savic need to do this, then effectively counter-press to maximise their scoring chances as Brazil seek to recover.
It’s also worth noting that Serbia also need to make sensible changes during the game. While Brazil’s switches against Costa Rica made sense and worked, Serbia’s in-game changes were less effective. They sacrificed solidity for attack and a slightly higher press, in part because of Milivojevic’s yellow card, but played into the hands of a quick-breaking Switzerland. The same approach will play right into Brazil’s hands. But, if Serbia keep it tight, exploit the areas highlighted, and use set-pieces effectively, they can certainly pull off an unexpected win that could throw the tournament wide open
