The official broadcast suggested he was about 5 inches offside (less than your line), though even this assumes that only the colombian players' legs are to be assessed in the process. Unsure what the rulebook says in that regard.
Thankfully we won out on penalties anyway. We were the better team by far. Colombians were very keen on going to penalties, which I found quite puzzling.
Ospina made an outstanding save early on to keep them in the game, but was very average after and could have cost them if not for the tight offside call.
If Uruguay beat Perú as, everyone expects them to, Copa América is wide open. Chile-Uruguay has become a bit of a derby in recent years, so with the other semi-final being Brazil-Argentina it'll make for some intense and entertaining football.
Also, Alexis is back in great form. Hadn't seen him play like this since 2017. Hope he kills it for Chile and is too tired to transfer his great form to manU.
