I am defiantly in the CL for season 5, I've been promoted in all of my seasons but have not won any cups or CL yet, why?

My best finish in the Cup was the 1/4 and I've been in the CL twice and lost them both in the final, It's best too look at my Team showcase to see more detail about my team.

But I want to know like what is the best tactic, is my team good enough for winning cups and CLs, am I playing the wrong formation? etc...

If you want to know more, just ask.
