FM13 is much more realistic than Fm12, you cannot just buy the best 11 players and use the same tactic for years and years and expect to win
I have an Aston Villa save where Im about 20 years in, and I have won 13 titles, 13 Champions Leagues, insane amount of cups etc. And I didnt win a trophy for the first 3-4 years.
I never change tactics, I never use shouts, I rarely even change the attacking philosophy during late stages of games. I just buy all the top young players around the world, use the good ones, re-sell the ones who dont turn out as expected and re-sell any that pass 28 years old.
I have a ridiculous stadium, I have £600m in the bank and Im the richest club on the planet by a mile.
I cant take all the credit though, I honestly think that Modern Warfare 442 is borderline cheating!
