First, I need to check the availability of such an update. FIFA 14 was released in 2014, and EA usually stops supporting squad updates after a couple of seasons. But the community might have created unofficial patches. Unofficial updates can sometimes be found on forums or sites like The Master League. However, there's a risk with these files—they might be outdated, contain malware, or not work correctly. Since the user is asking about a 2022/23 update for 2014's game, even the best community patches might not cover all seasons in between due to game engine limitations.
