Before a soccer game, every coach has to decide how they want their players to position themselves on the field. Each formation has its own objection, advantages, and disadvantages, including the 5-4-1 formation.
A 5-4-1 formation is a shape in soccer with five backs, four midfielders and one striker. This is a formation that relies on the five defenders to stop any attacks from the other team's offense. If a team is overmatched or simply looking to tie a game, they may consider this formation as a more effective way of preventing goals from being scored.
With five defenders protecting the goal, it is very challenging for a ball to get past them. Coaches with very strong defenders should consider this formation because it is unlikely that the other team will pose a threat against a five player defense, not to mention the pressure put on by the midfielders when they're playing defense, too.
Like many of the other formations with a heavy defensive line, and especially a heavy midfield line, these players can often get pushed back so far that they play minimal roles in aiding the offense.
So, while your defenders may be doing an excellent job of preventing goals from being scored, your team is most likely not going to have a lot of offensive players in scoring positions because they are all pushed back on defense. This formation could be a challenge for getting goals for your team.
