Having a good league draw is crucial to winning the trophy at the end of the season. The problem is, for the most part, the league draw is completely random and you don’t know who you are going to be drawn against until day 3 of the season.
There is, however, something you can do to try and help you get a better league draw. This is where your friends list comes into play. When the draw happens, who you have on your friends list seems to be taken into account as you are often paired with one or more of your Top Eleven friends. Now, obviously, this only affects your friends who are at the same level as you, so we need to think about who we are friends with at our level, each season.
You should seriously consider unfriending anyone who is considerably better than you at your level as you don’t want to be drawn in the same league as them. The best way to manage your friends list is to scroll through other leagues at your level around a week before the end of the season and send friend requests to teams who will be at the same level as you next season but currently have a lower team %. At this point in the season, all teams will be near their maximum %, so you can judge who is likely to have a better team % than you next season and who is likely to have a lower team %. You should focus on becoming friends with the teams who have a lower % than you.
