A few notes
UEFA.tv requires a free account, so make one ahead of time.
LiveSoccerTV.com is not complete when it comes to tv broadcasts, so if you find yourself unable to watch it on UEFA.tv, it might be on TV somewhere in your area…
I say this because it only lists Denmark but the company who owns the danish rights also have the rights in entire Scandinavia, and I see two matches on live TV in Norway (Vsport+, Vsport 1), and the other two on their streaming service (Viaplay)
Atletico-Barca is on BarcaTV+, their paid streaming service, which has a free trial … though I’m not sure yet if works internationally.
It’s also not unheard of that rights might be sold in the next few days leading up to the start of the mini-tournament.
