Hi ZANETTI and welcome to Top 11
Tokens are one of the resources, needed by every Manager. And, as others already pointed out, you should think twice before spending them.
As valuable advice, try to stray away from bidding wars, as they are an easy way to lose valuable Tokens. I myself have lost quite a few auctions and trust me, it's not nice.
But fret not, there are ways to attain Tokens without buying them. You can complete offers and surveys ( You can find an overview of all available offers for your platform and region by clicking on the T (Token) symbol at the top of the screen. Simply choose the “Free Tokens” tab and click “Show Offers”. ), sign TV contact deals, which are located in the "Finances" menu, selling players to other Managers via the Negotiation feature (available when you reach lvl 4) and from reffering friends to Top Eleven.
Oh and lets not forget the Football Associations (FA for short)!
Not only can you earn a good amount of tokens at the end of each season (and boosters each week) but you will also be playing together with your friends. In the FA it doesn't matter how far in to the game your friends are. Together you can group up with them and create an association, where each week you'll play a football tournament against an opposing association. Check out our online F.A.Q. where you can watch a whole tutorial video about the FA.
P.S. Oh btw, my colleague Jeeves (The other Admin) wrote up a nice article that aims to help out fresh new Managers. He actually spoke how new Managers shouldn't just rush out with spending everything they have in one play session. Give it a read.
