A former Celtic defender has responded to a German media question about Bayern Munich's Champions League progression.
Ahead of the second leg of the play-off in Germany, Andreas Hinkel was asked by Frankfurter Neue Presse if Bayern were already through after their 2-1 win at Celtic Park.
Bayern lead the tie thanks to goals from Michael Olise and Harry Kane in Glasgow last week, with Daizen Maeda netting one for the Hoops.
However, Hinkel was keen to emphasise the challenge still facing the German team.
The ex-Hoops right-back said: "I said before the first leg that Bayern were the clear favourites.
"That hasn't really changed after the result.
"Celtic have a good team - but a lot would have to happen for things to go wrong for Bayern.
"From Celtic's point of view, they need the absolutely perfect day to advance.
"They would have to be top defensively, use their counterattacks, and also have the necessary luck in the game.
"You could already see in the first leg that they have some good players."
Hinkel also highlighted some of Celtic's key players, recognising the threat they pose.
He said: "In Germany, Nicolas Kuhn is particularly well known; he has developed really well during his time in Glasgow.
"Daizen Maeda is a player who is very dangerous in front of goal; he scored the goal in the first leg.
"And in midfield, they have Arne Engels, a player who I know from the Belgian national team and who I really respect."
The match tonight will determine who progresses to the last-16 of the Champions League, and both teams will be keen to secure their place.
