Celtic hero Chris Sutton says his old team must stand tall and show no fear against Bayern Munich on Tuesday evening.
Brendan Rodgers' men travel to the Allianz Arena for the second leg of their hotly anticipated Champions League knockout round playoff.
While a 2-1 home loss in the first leg was far from ideal, Celtic travel to Bavaria well alive in the tie.
They know more than anyone, though, that to progress to the last 16, they will need to pull off a seismic shock.
And Sutton has told them what they must do to beat Bayern in their own backyard: "They have to stand tall and show they don’t fear the mammoth task which awaits them," he said (RecordSport).

Ahead of Tuesday's match-up, a few selection dilemmas face Rodgers.
While Adam Idah has been in fine fettle since Kyogo Furuhashi's mid-season departure to Rennes, so too has Daizen Maeda, particularly when deployed in a central striking role.
If Sutton was in charge, he'd be unsure of who to play: "Daizen Maeda’s switch through the middle from wide after Adam Idah went off helped on Tuesday, and there has to be a temptation to play him there from the start in Munich with Nicolas Kuhn on one side with Jota the other," he said.
"However, I’m not sure. And, in any case, that’d be some slap in the face to Idah after his two goals away to Aston Villa."
Before next midweek even comes into Celtic's thinking, though, they have to take care of business against Dundee United in the Scottish Premiership later this afternoon.
Jim Goodwin's men are no easy customers and are the only team to have stopped Celtic from scoring in a game so far this season.
