A 4-4-2 formation is a shape in soccer with four defenders, four midfielders, and two strikers. We already learned about the 4-4-1-1 formation, so that will help us with the understanding of this formation, as they are very similar.
The two strikers are the main offensive players for this formation. Similar to the 4-4-1-1, they are the gamechangers, as they can set each other up for shots on goal. It is common for a 4-4-1-1 to switch between a 4-4-2 if the strikers are going to set up a particular play for a shot on goal.
With this formation, there are eight players who could be deemed as defenders if the situation warrants it. With a number that high, there is a very good chance that the team would be able to steal the ball and change the direction of play within seconds.
Playing with two strikers can be a risky choice if the other team's defenders are strong. The two strikes have to be quick on their feet and see the field with one glance and know where the open gaps for passes will be. There is no reason why the two strikes won't be able to get past the defenders, they just have to know their half of the field very well.
