Once a player is given a red card and sent-off, game tactics change drastically for both teams on the pitch. Depending on the scoreline and what’s at stake, a few traditional approached are taken to dealing with one less player.
Let’s analyze the team that has just lost a man. In a traditional 4-4-2, the most common tactical move is to appoint one player as a lone forward, and the remaining players will maintain the same formation. So, your new look will be a 4-4-1. Again, depending on the circumstance of the game, a 4-4-1 might be too conservative. If you are desperate to score a goal and tie the game or win the game, you might want to take away a midfielder rather than a forward. What this creates is a 4-3-2 formation. Nonetheless, a 4-4-1 is your best option.
