A European trophy in the modern era is something they could lord over us for decades. The fact that they cheated to win the biggest fluke of all time will be irrelevant.
The only potential positive is the same as last year, celtic high commanded needed a serious shake and 55 delivered it, scottish football is better off for it, and this sevco run could have the same effect.
20 years of managed decline saw Celtic go from unbeatable at home at the highest level to an absolute gimmie for any semi competent team. Year after year, expectations lowered, hope crushed, and sevco have just exposed the cant compete bullshit that lawwell has been selling the rhetards. Not once in the last 10 years were we ever prepared for qualifiers, was all about player trading model and take what we get from Europe.
A couple of years under rodgers showed promise but it wasn't built on, and lennon had a few anti football hauntings but apart from that it's been monumental underachievement given the clubs resources and potential. I think starting from next season there will be less acceptance of failure in Europe but with Anges style of play and refusal to use PEDs its odds on to be more of the same.
