Decrease your avg lvl. But, then don't complain if the League or CL is too hard. Some call it a cheat, but it has it's downsides too. Winning a double is relatively easy, be it league and CL or league and Cup. Winning the treble should be difficult.

I am going to do exactly that with an account that has been in a slump for 2+ seasons with a 6* avg. I'll try and buy as many 4* 18/19 yr olds I can before the new season frenzy starts.
