Possession play

G'day lads, I've recently decided to switch my playing style and decided to play a more possession based game. Fell in love with the 4-3-3(5) but I'm still kinda average on using this formation. I know it takes time to get used to it but does anyone here know where I could possibly watch pro players or maybe even youtubers who uses this formation? I have searched on this thread and managed to find a guide but I'd like to see a visual representation so I can understand it more. Thanks in advance 😊
