We should commission a study into what happens to football teams immediately after a big game when they need to play a less illustrious opponent. This week Kilmarnock got a better result against Celtic than Barcelona, and unlike the Catalans, Kilmarnock were away from home.
Cast your memory back five years for a better example. Celtic beat Champions League holders, Milan, remarkably the only time the club have recorded a win against reigning champions, and met Gretna the following weekend, at Fir Park, Motherwell. Gretna were promoted that summer but had cutbacks forced on them, as the financial gamble to promote them to the top flight. Still, a James Grady free kick caught Artur Boruc on his heels. It took goals from Chris Killen (remember him?) and Scott McDonald in the final three minutes to save face for Celtic. Gretna failed towards the end of that season and were subsequently liquidated.
Celtic got the better of both Spartak Moscow and Benfica that season.[calameo code=000390171cd9e78b9c085 lang=en page=130 hidelinks=1 width=100% height=500]
