In this game you not only improve your own skills. Your players get better over time as well. When you play matches your team will earn experience points (XP). When you have accumulated enough points your team will gain an experience level. You will begin with 0 XP and Experience Level 1. For every match you play you will gain XP. If you win you will gain more and if you lose you will gain less. When you pass a certain amount of XP you will advance to the next level.

The number of experience points needed to advance to a new level increase with each level - so you need more to go from level 11 to 12 then you need to go from level 1 to 2. The Experience Levels are as follows:

Your team earns experience by winning matches. You will gain more when you win and less when you lose. The number of points is then modified by the difference in experience level between your team and your opponent's team. Winning against a better team earns you lots of experience points, while losing against a less experienced team won't give you many XP at all.

Each time your team gains an experience level you get the chance to improve your players. Select “Skills and Tactics” from your team page. Each player is given a number of points to distribute between his different skills. Your outfield players are given 8 points each while your goalie gets 5.
Click on the small green plus next to a skill to increase it. You must allocate all available points to a player before you are allowed to save the new skill level - and you may not add more than half the available amount to any one skill.
Choose skills to increase with care - taking into account the player's position and your preferred style of play. Do you want your attackers to be extra skilled at avoiding tackles or do you want them to shoot better?
When you are done with a player click Save and then proceed to the next one.
