All players have a current form and an average
form. The form varies between 0 and 20 with 0 the lowest, 20 the highest and 10 the norm.
Note that the form bars you see do not show exact form but a value rounded off to the nearest whole number. The higher the player's form the
better he/she will perform during matches. If his/her form is below 10 he/she will perform below his/her normal capacity and if it is above 10
he/she will perform above his/her normal capacity.
The form decides how the player's skill will develop
After each season players are updated and their skill level can be raised or lowered.
This depends a lot on their average form over the whole season. A player who has been in good form during most of the season has a greater chance of having his/her skill level raised than a player who has been in poorer form who instead is at greater risk of having his skill level lowered. In other words form is relatively important. When you select your team it is often better to choose a player in good form ahead of a more skilled player in poor form. This is of course only true if the difference in skill is not too significant.
Players will have their skill level raised or lowered between seasons depending on their average form over the whole season. Therefore it can be good to try and keep your players in good form and to do this they need to be playing matches and you can also order individual form training for a player.
What affects the form
A player's form will as mentioned above also depend on how well he/she performs in a particular match. For example, a goalkeeper will raise his form if he/she makes a lot of good saves but his/her form will be lowered if he/she lets in a lot of goals. Defenders will raise their form if they do not give the opponents too many scoring chances. Midfielders will raise their form if they create a lot of scoring chances. Attackers will raise their form if the team often scores when having the opportunity. Furthermore form also depends on individual factors. A missed opportunity to score will lower the form slightly especially for an attacker. A player who misses a penalty will also lower his/her form slightly whilst the goalkeeper who saves it will raise his/her form. There are in other words a lot of things that can affect form. In addition to this the normal form update will also be a big factor when it comes to form changes. Read more about these below.
How the form changes are calculated
Increases in form are always percentage of the form the player doesn't have and form reductions are always percentage of the form the player has. The maximum form is 20 form bars so if the player has a current form of 18 then it is 2 form bars that the player doesn't have. This means that increases in form will be smaller the higher current form the player has and form reductions will be bigger the higher current form the player has. As a result of this the player's form will tend to go towards the norm. Read more about the norm below.
It is also good to know that players' form is always drawn towards the norm, which is 10. This means for a player in good form further increases will be smaller while reductions will be larger and the opposite is true for players in poor form. You can liken it to a rubber band hooked on 10 form bars making it harder to stretch the further away from normal form it is.
The norm is not the same for all players. As the player gets older (30+) the rubber band is hooked at a lower form proportional to the players age. This means that a player who is 35 years old will have a form norm on around 5-6 form bars instead of 10 which is the norm for players in their 20s. Very young players will instead have a norm over 10 form bars which means that they will easier contain a great form.
Every time a player's form is updated the player will get a new form status. The average form the player has is based on the form notations that the player has had after each competitive match during the current season. The average form is important because it along with match experience forms the basis for the development value that is deciding the skill level update which takes place at the season update. Therefore it is important to try and keep the players in as good form as possible especially the younger players since they have a greater potential of raising their skill level than older players have. If the player have had too low form and/or played too few matches during the season the may reduce their skill level. Read more about this in the section about the season update.
The hidden form tendency and the normal form updates
A player's form is influenced by a hidden form tendency which every player has. If this tendency is on its way down the player's form will be drawn downwards and vice versa. The form also depends on how players perform in matches. Players' form is updated before every match. The hidden form tendency affects the direction in which the form changes, how much it changes depends on a player's current form as well as a random factor.
The hidden form tendency decides the direction of the form change at the normal form updates before each match. If a player has a negative form tendency his/her form will be drawn downwards and vice versa. The hidden form tendency is, as its name suggests, hidden and you cannot see it. It can change at regular form updates but can also change at special events for example during matches. A player in good form will more easily get a negative form tendency than a player in poor form. A player in poor form will more easily get a positive form tendency than a player in good form. It is however always more likely that the form tendency remains unchanged. The form trend for a player can turn to positive through form training. There are no guarantees but the chances are good it will happen and they are greater the poorer the form of the player.
