Ball possession shows what share of playing time the ball was under the control of each team. For example, 60% for one team corresponds to 40% for the other. High possession does not necessarily mean more dangerous chances or a lead on the scoreboard.
Possession and pressure are not the same thing
A team can control the ball for a long time in its own half and create almost no chances. Therefore even 60–70% possession does not yet mean that it is more dangerous than the opponent. It is important to take into account where and for what purpose the team possesses the ball.
What to compare possession with
- High possession together with shots and dangerous attacks may indicate pressure.
- High possession with a low number of shots may mean ball control without creating danger.
- Low possession is not always a disadvantage: a team can play effectively on counter-attacks.
In algorithms possession is best used together with shots, dangerous attacks, intensity and other metrics.
