It's difficult to make friends on T11 I think and to try and get other managers to support your team, especially you can't talk to anyone, because I'm sure I'd talk to a few saying good game or even congratulate someone that gets a result against us. Even the Batigo United or LIVERPOON manager. I even would of said "well done" to the Fc RonnyBonny manager for trying to beat us a while back in the Champions League when he watched both legs of the Semi-Final.
Some just try to add people to troll for friendlies and it's not nice, If nordeus sorted the "mutual agreement" thing out with friendlies, I'm sure more honest managers would send out ingame friend requests.
