Maybe that's because unstable rules. There were times not so long ago when supports could use it. They've just used to them. Not to mention even in the football game there are flares (not only at places where are most aggressive fans, but everywhere). It's not that effective, poor single ones, but still :P
No. Coming back from 2-0 down is not easy for any team especially this Celtic team. We don't play in the mighty Belgian league you know! Who would not be delighted when their team reaches the Champions League? And judging by the celebrations of the players tonight, I don't think they would find it pathetic either.
Anyway what's the matter, did your team get put out or something?
No, my team didn't even reach the CL-qualifications, and they didn't reach the group phase of the Europa League either. However, that has nothing to do with this. A Scottish top team should always easily defeat a Kazakhstani team. That's the point.
Edit: Maybe 'pathetic' was not the right word. 'Sad' would have been better.
