I fthe ame don't have enough teams in a level, just add teams of a lower or better level to complete the leagues... This situation happenned to me 3-4-5 teams... so, probably with his team he played in a league +1 level... like I did some times,,, then you have a 7* scout list too if you play with level 15 in level 16 for example.

And till here my theory.
