this is good but a good tip
To win games on FM15 is easy when you have the right tools eg this tactic . I've found that you don't need the best players. If your tactics and training schedules work, you'll win games with no problem. If you are conceding too much, alter your team training schedule; put your GENERAL TRAINING on DEFENDING on VERY HIGH and move the bar all the way to LESS MATCH TRAINING. However, put your MATCH TRAINING SCHEDULE on ATTACKING MOVEMENT. This way your team can create a lot of chances whilst no opposition can break your down your defence. I did this with Sheffield Wednesday who are a poor team .I won the league and after I got promoted i got champions league the next season.
