5 mammoth Celtic decisions to make as blockbuster Leipzig clash to decide Champions League fate

Celtic boss Ange Postecoglou hasn't been short on iconic soundbites since arriving at Parkhead last summer.

And his "champions, that's who we are" reflection on title day last season never felt more relevant as the Scottish Premiership kingpins sickened St Johnstone after Giorgos Giakoumakis' last-gasp winner – around two minutes after Alex Mitchell's injury-time leveller at McDiarmid Park. The character and belief running through Celtic cannot be questioned. However, they head into their blockbuster rematch against Leipzig playing below their best.

And 60,000 passionate punters on a Champions League night have a way to inspire but it will take more than a raucous atmosphere in Glasgow's east end to knock off big-spending RB Leipzig. Chelsea-bound Christoper Nkunku is a special talent and he headlines a front four with a market value in excess of £120million. This is no easy feat. But glittering opposition have been defeated before and a win for Celtic would see them reignite their dreams of reaching the last 16.
