How can I play FIFA 20 on PC today?

Hi everyone, I’ve never owned FIFA 20 on PC and I really want to play it today. I know the official EA stores no longer sell it, so I’m wondering:

• is there any legal way to get a copy or a digital key?
•  Can I still play it offline if I manage to get it?
• Are there any alternatives or workarounds to enjoy FIFA 20 on PC now?

Any advice or guidance would be greatly appreciated! Thanks in advance!
