There are several Irish bars in the centre. Dubliners and O’connells are in Sol and will most likely have a few tims in there.
If you walk 10 mins to Calle Alcalá, next to Cibeles fountain, there’s a pub called James Joyce. You’re less likely to get any hassle in there, but it’s busy enough and there’s a few big screens (to be honest, I doubt you’d get much hassle anywhere).
It’s also right next to Retiro, so after the game you can continue your visit there.
