See I'm not a ST holder myself but when chants like 'Come On City' and 'Blue Moon' ring around the ground I can't help but want to join it but it's a shame when the people next to you make you feel like you're the only one singing it so you refrain from singing it. I had people around me taking too many pictures and videos during the games of free kicks etc. Had a guy near me to me even recording the screen when the VAR decision went up for the red card (wtf?). I'll be getting a ticket closer to the singing section or the south stand next time. I was lucky enough to be in 308 for the Madrid semi last year and despite the fact I'm a bit scared of the height, I will never forget the atmosphere during that game. Also going to add that it's slightly annoying when people happily come in late and try and find the seat and obstruct your view of the game. Everyone has their reasons for being late and I respect that, but too many people do it for me.
I agree with what you said, I think it was a good win but we needed to go for the jugular after the second goal and score a third before half time. I don't know why but the game and atmosphere fell flat after the second goal went in for the remainder of the half. Again like you said, I felt once the red card happened and ederson's YC, it was very tense for me, but I also was a bit surprised that forest didn't do much. The crowd overall were good, heard 'Come on City' start in one of the blocks around the north stand at one point and thought it was quite classy. Also saw Pep rally the crowd and thought that helped too.
