Is Oliver Abildgaard man to fill Celtic skipper Callum McGregor's boots and can St Mirren stun Rangers? Saturday Jury

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.

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.

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
