I did it like Beckstar. In my lv4 season, I follow this tactic, sold many 5-6* players, got 4 3* players last day who became 2* and with the rest 5-6* players I had an easier Cup draw in lv5. LV5 in a LV7 Cup. Actually the lv7 teams were few and in a low quality. I sold my 2* players in the first day, bought few new 5* players plus a 6* scout/list and won the Cup playing against a lv5 team in the final. This season I also won the league and the CH.L. so I get my first treble.

Difficulties : I had a very difficult league against many teams 5-6* players. I also had every day one extra difficult game in Cup or CH.L. so I must had many good players for rotation, red packs for the injuries and green packs for training because I had to develop my players so having advantage against my opponents during the season.
I had to be lucky and don’t get a first game in the Cup against a good team because I had to find good players asap.
I didn’t find any good ST so I played the season with only 2 ST and 4-5-1V formation.
I was lucky that all my players had a very good season.
I didn’t have any troll results in critical games like semi or finals.
It isn’t so easy as it looks but at least you have few more chances. Of course it needs concentration and following the game daily.
