This game realy sucks, if the computer don't want you to upgrade to another tier, they do everything to frustrate you, even if your opponents players are under 60 and 70, they make your players to be really slow and tired very fast, or your players get injured at the slightest touch and every shot you shoot on goal either hits the woodwork or the keeper hits it or it goes out, how can a player under 70 chase a player above 80 and retrieve the ball from the player, why spend money on upgrading
