4 controllers in FC25 on PC

Hi,

I wonder the answer for that question too.

Unplugging keyboard and mouse might work on PC in my opinion. But I'm not sure about laptops.

I will try when I have the opportunity.

 I've been scratching my head over this for 2 days. So I bought the game 2 days ago and now am skeptical about controller support so I can't yet order the controller and can't play the game and it is killing me. Sorry, my queries:

1. How did you even manage to connect 3? Tell me the entire process PLEASE
2. you mentioned 2 wireless 2 wired, how did you connect them? 
3. I have a laptop, would I require a powered USB hub? I'm planning wired
4. Me and my 3 friends just wanna enjoy kick-off offline at my home, just tell me how I connect 4 controlers
5. And if there are any potential headaches in this setup
