Firstly, Welcome to the game!

Your match attendance is capped at 1,000 fans without having a Premium subscription.
- See: https://www.virtualmanager.com/frequent_problems/24?query=Stadium

The system is preventing you from wasting Credits on an Upgrade that you wouldn't benefit from.

You should not dive in and purchase Premium without giving it some thought first.
You can play this game forever for free but with certain limits - like this one,

- give it a while to see if you enjoy it before considering whether it's worth the price of a cup of coffee every month to pay for the subscription

oh ok thanks
