How do I win every game

To win every game, it is recommended that you get an excellent team, like Real Madrid, Barcelona or Bayern Munich, and then you just play the matches with the best squad you can make. I suggest that you rotate players in order to maintain high morale within your squad and to rest your starters for big matches. If you want good players to rotate, buy some 80+ Rated Young Players like Santi Mina (From Valencia) for example. Romania has a few good players, Penarol has a young Uruguayan called Valverde who is a promising talent and train your players according to stats (If they're highly rated) or train players to develop good stats (If they're young). Also, get some of the free agents during the transfer window which cost half of what their value is (Example: If a free agent is 3 Million in value, you pay 1.5 Million for the player). Also, don't be afraid to use SM Coins to get players, I have used SM Coins to buy back Iker Casillas onto Real Madrid. Also, some ideal tactics if you want a good balanced team would be a 4-4-2 or a 4-2-2-2. Attacking would be 4-3-3A (If you want some good counter attacks). To finish off, have your best player take penalties, 2nd best take free kicks, best midfielder take corners, 2nd best midfielder do playmaking (I Have Ronaldo doing Penalties, Bale taking Free Kicks, Kroos making Corners, and Modric making plays).

First of all, choose Real Madrid or Bayern Munich. Use the counter formation system to break their defence. Use 433A or 422A. These are the most stable ones.
