I reckon its the active friend thing more than anything else. I do it from 1/4 finals onwards because there is a good chance the other manager is active.I did it a lot at lower levels to build up a big bank of hopefully active managers that will continue to supply you with the daily packs , its 28 greens per season.

Nahh... this game is unpredictable lol... no need to test opponents to win... sometimes when u against 3 star2 team u may also lost... its oke lol to find new friends after allπππππ
usualy it is just to be friendly, sending gifts or support, but i have also one experience when league member sended request and than started to suport my oponents, not just in league but in CL and even special event as well, so i delete him after 2 days, tried to send me request few more time but i ignored him
I send friend requests to other British players and players that support my current friends games, as I also try to do. Can give you an advantage .
