The first World Cup semi-final takes place on Tuesday when Germany meet hosts Brazil in Belo Horizonte.
Brazil have the benefit of a passionate home crowd but are without two of their best players.
What's more, their quarter-final win over Colombia came at a cost. Thiago Silva is suspended after picking up a booking, while Neymar will sit out the rest of the tournament with a back injury.
Germany, meanwhile, enter after a composed 1-0 win over France. With that victory, they became the first country to reach four consecutive World Cup semi-finals.
Here's a rundown of six players to watch on Day 27 of the World Cup.
