3 ways:
1-st use green packs
2-nd buy 22 equal players
3-th if you have home game you can postponed match with few hours for 2 tokens
aye but i don't have enough money to buy other players, and also i signed 1 or 2 players at the start of the season and it told me that i had to sell/sack someone so that i could make this player sign a contract? so i couldn't have a bigger squad?
