i was in your situation when i want to wake my second account up with entire team is 32-33 non retired player. it's was level 22 , easier than your level. but i have something if you need to secure your team. if you have time. don't worry. you need to sacrificed one season to make your team a durable support financial

-First thing to do , You play at least 3 friendly matches a day at that will give you enough money for survive. Don't care about player condition or injury. just do it.if you have 260k stadium you should set a ticket price for these matche about 23 $.
-SET ALL bonus money to 0$
-Buy FREE player. check for 3* low end (Q150-152) but YOUNG (18-23) because you can resell them when he reach Q154(your level is 29). nobody buy them at your level because of expensive. keep your team as crowded as possible. even Nordeus sell these player, you're still have 35 M for 1 token (sell 75 M but you need to buy 40M). it isn't something worse.
-When you have 22 player team. you'll never scare about financial problem at least at level 35 by just play 3-4 friendly matches with 11 players in reserve squad.
-now it's near to the end of season. Never renew contract, wait for day 1 next season. you can have some 32-33 yo player free
