Average Age Rule

Another factor which contributes to the success of your team is the average age rule. This relates to having your teams average age to 26 years as possible.
This means that a junior-only team will underperform. You'll need some veterans in your team to get the correct balance.

It is the performance of the team part that is affected if the average age is less than 26 years. How big the performance reduction will be depends on how much lower the average age is in the team.

For example if the average age is 22 years then the team/team part* will perform about 85% of its capacity. If the average age is 20 years then the team/team part will perform about 76% of its capacity. If one team part has an average age higher than the other the one with the less average age will gain a little age and the other will lose some age. This means that if you have a team part, for example the defence with an average age over 26 years it will compensate the lack of age in the other team part to some extension but there will still be some reduction on the "young" team part's performance.

*Team part relates to defense/midfield/attack

The rule affects TWENTY percent of the final result. So try to spread the age in your team and keep the average age around 26 or 26-plus.

The most successful managers are the ones who ruthlessly stick to an average age of around 26.
