I know how you feel,

I've been trying to limit spending as I spent a lot before in Lv1, Lv2, and now in Lv3 trying to save up until Lv4. I had one who kept getting red card, one of my 39 rating players so I sold him.

I had 3 players injured and are 5 days each. I then had 2 players red carded so they miss a match... and guess what just happened...

"Your players are well rested, time for some training" or whatever message came up, so I did a 20% training to all players, to give me some time to get them well rested before 11am tomorrow... Boom! Another player got injured and out for 15 days... It's pathetic!
