One day is more than enough if you know how to manage your squad, finances and tokens.
I find that on 1 token a day, I am short on cash rather than tokens. The only use I have for tokens is open market bids. If you know when the market is quiet ( as in bidders not around) you can get your player for n or two Ts. Know when to hold em,know when to fold em....as the great Kenny Rodgers once said... Still have no clue as to what he actually sung about.

As for my teams winning anything ..... On 1 a day... All are in the top 4.....but I am small fry...only level 3. I don't count.
