From what we've seen of Oliver Abildgaard, is he the man to fill Callum McGregor's boots in Celtic's midfield?
KEITH JACKSON: He didn't look up to the job on Wednesday night but it would be unfair to make any snap judgements based on that cameo. He'll need to get up to speed fast though because these are big boots to fill.
DAVID McCARTHY: He won't be able to replicate what McGregor brings to the team but the most important thing for the Dane is to play his own game and bring his qualities. But McGregor is a massive miss.
GORDON PARKS: The Dane looked a bit lost in Germany and needs to find his feet quickly if he's to capably fill McGregor's boots. He has the pedigree but can he pull the strings in the absence of the skipper, I have my doubts.
Surprise package St Mirren have already taken Celtic's scalp. Can they make it an Old Firm double at Ibrox?
KEITH Probably not. They'll be well drilled, organised and will make it hard for Rangers but home advantage should be enough for Giovanni van Bronckhorst to take another three points.
DAVID : They'll rarely go to Ibrox in better form or with more belief that they can get something. But Rangers looked strong at Tynecastle last week and should have enough quality to win the match.
GORDON : Why not? Rangers have issues all over the pitch and can be got at, but the question is whether the Buddies have the bravery to have a go. The approach which claimed all three points against Celtic also requires a bit of luck.
Robbie Neilson is coming under pressure again at Tynecastle after another European drubbing. Is his manager's jacket now on a shaky peg?
KEITH: It most certainly shouldn't be. Neilson has worked wonders in both of his stints in charge. If there are Hearts fans who can't or won't acknowledge his good work then they don't deserve him. He's the right man in the right place.
DAVID: No chance. He's made them the third best team in the country and a couple of scuddings as they find a whole new level in Europe isn't going to change that. He's there for the long haul.
GORDON: No. Hearts fans know their club has climbed back from the Championship in some style and are now facing top European teams. A sense of perspective from where the club has been should protect a boss who is the right man to continue all of that good work.
What's your thoughts on Jim Goodwin's eight game ban?
KEITH: It's an outrage. Not only was Goodwin spot on with his assessment of Ryan Porteous but there are players getting one or two game bans for tackles which could break legs. Goodwin was only guilty of hurting someone's feelings.
DAVID: It will be interesting to see the written reasons for the severity of the punishment as it seems ridiculously harsh. The fact that everyone was stunned to hear it was eight games says it all. Players get far less for tackles that can put the victim out of the game for months.
GORDON: Stunned. It's far too severe. Goodwin said what he believed and good for him. There is far too much policing of managers in the game and a censure would have been appropriate but this ban is way over the top.
