3-0 is not bad for Turkiye, it is a manageable result for them even though they are losing the match, they get this hype and hope of winning Portugal because of their performance in their first match, but I am very sure Turkey will qualify to the next round because they will definitely defeat Czechia in their last group stage match while I am also sure that Portugal will also win their to have a 100% performance in the group.
I think the Portugal team has more balance players than Turkey because almost all the players in the Portugal team are regular starters in their respective teams. The presence of Ronaldo is a big boost to the Portugal team but that didn't stop Turkey from performing well in the game become watching them today I saw a team that is full of fear in them, a typical example is the mistake that led to the own goal there was no proper communication between the defenders and the gowl keeper.
3:0 down and you expect them to level the scoreline that's amazing, Portugal has already won the game as the game ended long time ago and I think they are looking forward to the knockout stage.
