manage clubs

Hi. I can't find info about manage club's. I had my own club, but in manager account I saw clubs without manager.
If I take the one of these clubs then I can manage a both clubs or I lose my first club?
please help... :)

If you take one of those clubs, you transfer as manager from 1 club to another. Meaning you leave the club you were managing to manage the other team.

I have friends that manage multiple clubs, but they do it with multiple fb accounts and then assign a club to each account.

You can also have a second team if you don't mind it being linked to a single device, with the app.

But the Teams Seeking Manager gives away your current team like PaCe Ros explained. So that is only good option if you no longer love your team.
