The problem of determination of effectiveness of the forthcoming match has secondary character for a set of tasks. It shows the efficiency of play of the team at home and away, allows us to compare tactical efficiency of the game of the team, to create the expected result. It is standard that it is impossible to predict result of the game. The algorithm of determination of effectiveness of future match through the system of the linear equations disproves this statement and brings us to the solution of many key tasks.
