Celtic return to European action after Christmas for the first time in three years when they take on Russian side Zenit at Parkhead in the first leg of the Europa League last 32 tie on Thursday.
Brendan Rodgers will be under no illusion about the difficulty of the match, against a team that have been assembled for millions and are managed by the former Premier League winning manager Roberto Mancini.
There’s also the Hoops’ poor home form in Europe to deal with, as they haven’t won any on their last six Champions League group stage matches, including three earlier this season.
Some players such as Moussa Dembele and Callum McGregor have been badly off-form, and they will have to up their game significantly if the Bhoys are to progress through to the next round.
However, the biggest issue could be the Hoops injury list, with the likes of Craig Gordon set to miss out.
