Yep. You've got to the point where you've noticed. At level 28 the cap is 111 million (I think). So that's how much player values are going to increase over the next 12 seasons for you.
On the good side. If your stadium and other facilities are maxed out or almost there, and if you're consistently getting good results, the next 4 or 5 seasons will see you realise that money becomes useless. You'll have nothing but players to spend it on.
Push through the next couple of seasons and you can forget about money.
