Manchester City - Money problem?

Hej guys!

I've started a game with City and I have experienced some mystical situations about their economy and transferbudget.

- So, they have around £10m in starting transferbudget, and have 100% transferdisposal.

- I sell two player for £44m, and leaves me back with £25m transferbudget, instead of £54m

- After buying a player, I had £10m back, but suddenly £8m dissapears from the budget, with me doing nothing?!

Can anyone tell me, why is that?

Probably to do with their sanctions with the FFP.

Maybe your right, I never thought of that..
