7 different people get together to play their favourite game. These people are very predictable, and they each have a different amount of skill at the game. Each person will always defeat anybody with less skill than them.


These 7 people play a tournament, where each person plays 2 matches with 2 of their peers. Every person who wins both of their games is a winner. What is the maximum possible number of winners?
