It can be very frustrating when you can't seem to find a win. I had a brief look at your team to try and figure out why your team is not performing well. Your best player is crippled by injury while most of your other players are getting up in age. As your players are getting older, they are loosing skills with each passing day, contributing to the decline of your performance levels.
My suggestion to you would be buy players to offset the declining abilities of your players. You may want to consider moving a few players along or releasing some of them due to their ages and declining levels of performance. Try to buy some young players with good potential.
You might also want to take a closer look at your technical decisions in games. Understand that your team doesn't look very dangerous in attack and I suspect your defence isn't so solid either. Start on a new page with player evaluations. Determine who is fit to remain on your team and start training everyone with the team philosophy in mind. In this way, you will experience team improvement rather than just promoting the individual qualities of your players.
My club is having a player sale currently selling young talent, the kind of players you will need to invest in to promote effective growth of the team as a whole. The market is prime for getting good players at very low prices so doing some shopping for players might be a good idea. I am sure you can find the kind of players you need without breaking the bank to do it.
Keep in mind that change doesn't come over night in this game. A few good signings will make finding a win easier, but you will still need to make good buys for you club as well as focus more on your tactical strategies during each match. The post game analysis should help you determine when you are making good tactical decisions.
