A little guide for people.
The teams: The better the team for example - Chelsea,Arsenal,Man utd will have players in the squad with a lot higher ratings than lower teams. Each teams have different goals and you want to beat this, of course everyones goal is to win the league. Note it will be hard to do this with the lower teams.
Training players: You need to hire the four trainers and train up the players in the squad. In pre-season which is now that lasts for four days i reccomend training up the key players in your squad you will use in the season, if there age isn't too high that is. For players to gain much in training i advise 16-28 maximum, the lower the better chance. You should also sell the lower rating players as the computer can buy them from you giving you money to buy new players to improve squad. Note: only season ticket holders can use scout to scout players from any league, normal accounts can only buy players on the for sale list.
Tactics: Your tactics work different agaisnt each team depending what tactics they use. Your best to expierment with tactics and find out which best works for you.
The league: You will have to wait til tonight from 12.15 onwards to join a team, as first day is only for season ticket holders.
Just have a look about all the options and you'll find everything easy to grasp i'm sure. And don't worry if you haven't got the best team, or your team isn't winning all the time. Just try get above the rank your team board wants! Although it is good to have a good team too sometimes
Make sure that you get sponsors for you're team as this is a main source of income, aswell as selling players. If you have a season ticket you can get extra money from stadium upgrades.
