We already have form, but we only can see the last 5 games.

Like in FM for PC we should have a season rating for each competition.

Example: a player performs this during 7 games --> 7.8 ; 6.9 ; 10 ; 8.2 ; 7.6 ; 6.5 ; 9.8

(7.8 + 6.9 + 10 + 8.2 + 7.6 + 6.5 + 9.8) / 7 = 8.1

Rating of that competition: 8.1
