Try adding him as friend with your 2nd account or so.
no, it can't be done. My second team (Artemis) doesn't know him yet
Will meet him tomorrow, when it 'll see the schedule of NIK F.C.
but tomorrow, early in the morning, there will be the announcement about qualified in the final and the hour would be already set up.
Only my first team NIK FC knows him and must make the friend request today, so I can see his program for Thursday.
But will he accept ?

Also, I can't fix a friendly from today, for Thursday (morning for example).
