No, and I strongly recommend avoiding all unauthorized streaming sites — many of them host pirated World Cup content, so they’re breaking the law, while others might host malicious ads and links, which could infect your device with malware.
Even if you find an unauthorized site that seems okay, the streaming experience will be very poor — the broadcasts usually have poor image quality, will lag very often, have choppy audio, and lack commentaries. In addition, annoying pop-up ads might disrupt your viewing experience. Plus, these sites can disappear overnight since they’re illegal, which will leave you with no way to watch the rest of the World Cup.
If you really need to watch the FIFA World Cup for free, you can do so on BBC iPlayer — and if you’re not in the UK at the moment, you can use a VPN (like ExpressVPN) and connect to a UK VPN server to get access to it.
