Another embarrassing result in Europe, don't matter if it's PSG or a diddy team from Andorra, Celtic should never be beat by this margin. Can't make excuses here, shouldn't be in awe of tonights opponents, if Celtic want to make a mark in European football then they have to start stepping up and get rid of the Scottish 'at least we're here to make up the numbers' mentality. Team still has a couple of things that need remedied: Goalkeeper - Craig Gordon good shot stopper but distribution still poor. Was at blame for two goals today at least. Right back - Lustig has not got the fitness level anymore due to his numerous injuries. Needs a solid replacement Centre back - Boyata and Simunovic are good but not great, Celtic need a marquee defender (or two) to come in. It's shocking how we've had to play at least 3 of the biggest games of the season with makeshift defenders. Defensive Midfield - Brown is the club captain and the driving force but I think can no longer play at this level and is getting found out in a couple of European matches. Can he be replaced though?
