Why cant I send negotiation offers?

Jos is right, your friends aren't from the same server.
Find a team (from your Cup/CH.L. for example), and see if you can make an offer to one of his 5* players.
If it's working, that's the answer.

Ahaha, it works for my Cup opponent, could send offer to him.
So it's impossible for me to send offer to my friend? Do the server switch among each others??
