Imagine a game of football that you are watching on TV or in a ground.

If a team is lined up with 6 defenders, then they have 3 defencive playing midfielders with one loan striker, how does the striker get into the game?

If your opposition has 5 midfielders across the middle of the pitch and you only have two on each wing, what happens? - the players in your opposition will run down the middle and score.

It's all about making sure you have players in the right formation and right position to assist each other. A classic 4-4-2 has good balance and if you have players in the right position doing the correct things then you will be able to "feed" your strikers.
