According to what I've seen on social media, it seems like Ranger fans aren't happy with their team's performance either. Some of them blame the coach, while others blame the players. It feels very unhealthy atm, which is expected to happen if your team loses and has bad form. At the end of the day, recruitment is usually one of those problems. Not sure if they can salvage it this season. Even their league form is pretty bad, let alone UCL qualifiers.
I don't know why they underestimate all the competitions like this, they have had a significant decline and it can be seen and felt in all the challenges they have to face, I'm not saying that they should aim to win the Champions League but at least work towards a better form.
