Arsenal's hopes of reaching the UEFA Champions League quarterfinals are in the balance as they look to overturn a one-goal deficit at home to Porto today at the Emirates Stadium. 

The Gunners were left stunned last month as Brazilian winger Galeno scored a stoppage-time winner in the reverse fixture at the Estádio do Dragão, giving the Portuguese side the advantage in this last-16 matchup.

David Raya is set to return in goal for Arsenal, but the hosts will be without Gabriel Martinelli, after the forward picked up a foot injury last week. 

Porto, meanwhile, welcome back defender Wendell for this clash after his recovery from a thigh problem, while Iranian striker Mehdi Taremi is due to have a late fitness test on an adductor injury.

Below, we'll outline the best live TV streaming services for watching every game wherever you are in the world.

How to watch Arsenal vs. FC Porto online from anywhere using a VPN

If you're unable to view Champions League matches locally, you may need a different way to watch the action; that's where using a VPN can come in handy. A VPN can stop your ISP from throttling your speeds on game day by encrypting your traffic, and it's also a great idea if you want an extra layer of privacy for your devices and log-ins while traveling and using various Wi-Fi networks.

With a VPN, you're able to virtually change your location on your phone, tablet or laptop to access the game. If your internet provider or mobile carrier assigns an IP address that incorrectly shows your location in a blackout zone, a VPN can fix that problem by giving you an IP address in your correct, non-blackout area. Most VPNs, like our Editors' Choice, ExpressVPN, make it really easy to do this.

Using a VPN to watch or stream sports is legal in any country where VPNs are legal, including the US, UK and Canada, as long as you have a legitimate subscription to the service you're streaming. Be sure your VPN is set up correctly to prevent leaks: Even where VPNs are legal, the streaming service may terminate the account of anyone it suspects is circumventing correctly applied blackout restrictions.

Quick tips for streaming UEFA Champions League matches using a VPN  With four variables at play (your ISP, browser, video streaming provider and VPN), your experience and success when streaming Champions League games may vary.If you don't see your desired location as a default option for ExpressVPN, try using the "search for city or country" option.If you're having trouble getting the game after you've turned on your VPN and set it to the correct viewing area, there are two things you can try for a quick fix. First, log into your streaming service subscription account and make sure the address registered for the account is in the correct viewing area. If not, you may need to change the physical address on file with your account. Second, some smart TVs including Roku don't have VPN apps you can install directly on the device itself. Instead, you'll have to install the VPN on your router or the mobile hotspot you're using (like your phone) so that any device on its Wi-Fi network now appears in the correct viewing location.All of the VPN providers we recommend have helpful instructions on their main sites for quickly installing the VPN on your router. In some cases with smart TV services, after you install a cable network's sports app, you'll be asked to verify a numeric code or click a link sent to your email address on file for your smart TV. This is where having a VPN on your router will also help since both devices will appear to be in the correct location. Remember, browsers can often give away a location despite using a VPN, so be sure you're using a privacy-first browser to log into your services. We recommend Brave.
