Stadium Unlockable questions

[DanscoFM]

I’m playing as Monza in Italy and starting my 6th season. I’m in the Champions League for the 2nd season running but my stadium is the one I got when I was in Serie C with capacity of 9k. I’ve asked the board several times and they don’t believe we need a bigger stadium but I’m filling out it every single game. 
I’ve been using unlockables before - some that I bought and some I earned so saw that the Stadium unlockable is there so my questions are about that:

* Will the stadium be a certain size like 100k or smaller like 70k?

* Will it take as long as a normal stadium? Like 2 years 

* Can you name it like a normal new stadium?

* Most importantly will it take money out of the clubs accounts? Like cause them to take out loans or cause money problems? 
 

I just want a new stadium. Thanks
