One thing to add about unfriending Managers in Top Eleven.

Keep in mind that there are two categories of friends:

1. In-game friends - You invite them to be your friends by opening their profile and sending an invite (You have to be able to see them in ANY of the competitions ofc.) To unfriend them - Quote from dave1311 "... simply go to their profile and tap the Red x in the top right corner of their picture."

2. Facebook friends - These are automatically added to your friend list IF they also play Top Eleven. To remove them as Top 11 friends you have to unfriend them on Facebook.
