For 1* you need to plan long term really.
Don't be worried about the odd season 'tanking' (purposely not getting promoted to consolidate the team and save up reds and greens).
Here's my squad this season, I'm top of the league, through to CL KO stages and looking good in the cup as well.
My top player is Q130 and my lowest player is Q68.
The 68 quality player is 30 yo and has been in my squad since an academy youth, as have all my 1* players.
All the players highlighted in yellow are bought on the third day of this season.
Most of them will be sold on on the last day of this season along with a couple of others who have just reached 'past usefulness' stage so I'll start next season with probably six 5*+ players and eight 1* (I'll sign another academy player before the end of the season), I'll get rid of one of the 1* and fill the remaining places with 5* (hopefully close to 6* if I', lucky) transfers.
