we have every season at least 4 days with only 1 official game (the first 2, the last and the 3rd friday). of course other teams who do not progress in competitions have more single games but i am toking for the top clubs. there could be arranged these 4 days a super cup competition only for the clubs that have won the cl the previous season. a group of 3 teams playing each other 2 games (home- away) it's a total of 4 games for every team. it could be arranged the first 4 days of every season.
