Sandy Cochrane: Sorry to say it but this is embarrassing. Roberts is useless. Brown no better. ONLY boomerang balls being bashed out of the box.

Leigh Brown: Best chance they have of not losing is a floodlight failure.

ScMid: Saving themselves for the big one this weekend against Hibs.

A flurry of substitutions, with James Forrest replacing Patrick Roberts and the hosts throwing on James Rodriguez and Rafinha in place of Kingsley Coman and Joshua Kimmich.

They’re making a couple of chances since the fresh legs have come on. You’ve got to give them real credit for that. Rogic has made a difference.

Arjen Robben surges into the danger area from the right and Craig Gordon is brave, blocking at the Bayern winger's feet to concede a corner. From the resulting delivery, Mat Hummels goes close to another headed goal, arriving at the back-post but knocking the ball just wide.

A big opening for Scott Sinclair to get one back but he can only smash a shot straight at Sven Ulreich, who did well to close the angle from close range. The keeper then dives to push away a stinging follow-up from Tom Rogic.

Arjen Robben has a lot of time to pick his spot as Celtic are opened up by a smart Arturo Vidal pass. The crowd expect the Dutchman to curl one into the far corner but he doesn't execute with his usual ruthlessness and Craig Gordon gets a hand to it.

They’re not used to having to run around and staying together as a defensive unit. Normally they’re on the ball and this is really, really hard. I’m looking at Ntcham, I’m looking at Brown, they’re really on their knees. They can’t get into good positions defensively and it allows Bayern Munich just to cut them up.

Now Kieran Tierney has a go with a powerful, swerving shot from 25 yards. The keeper gets fingertips to it and the ball crashes against the post.

A nice touch and pass from Tom Rogic finds Kieran Tierney in space down the left and it needs a stretching interception to prevent Moussa Dembele connecting with the left-back's low cross in front of goal.

Thiago has strolled through this game in central midfield and now he's replaced by the human dynamo that is Arturo Vidal. He's not one for taking it easy, even at 3-0 up and cruising.

Paris St-Germain are matching Bayern all the way as Neymar notches their third against Anderlecht.

Fair play to the Celtic fans. Still singing despite their team being outclassed by this excellent Bayern Munich outfit.

Maybe that firestorm predicted by Mr Keys is coming... Moussa Dembele and Tom Rogic are on in place of Leigh Griffiths and Stuart Armstrong.

Archie McLean: As a St Johnstone fan I’m behind our European representatives. Great achievement getting to the group stages and competing against Europe’s elite.

John Bradshaw: A little perspective Bhoys & Ghirls. Bayern are 5 time defending German champs - by a collective 79 points!

Peter Keys: That's it lads,lure them into a false sense of security with a 3-0 lead, then throw on Rogic & Dembele for a 4 goal firestorm

Robert Lewandowski must wait if he wants a goal this evening. He nudges in a cross from David Alaba from close range but was half a metre offside.

Almost another goal from a corner. Arjen Robben finds room inside the box and his glancing effort needs to be hacked off the goal-line by Cristian Gamboa.

Arjen Robben works a neat one-two with Thiago before skidding the ball across the six-yard box. Craig Gordon does well to gather under pressure and, soon after, the busy Celtic keeper does well to beat away another dangerous delivery.

It all comes from the bad pass from Craig Gordon into Scott Brown initially and they give away the corner and they’ve been punished again.

Mick McCristall: Nothing funny about it, bad for Scottish football.

Andru Blakk: It's exactly what I expected. We've been poor on the ball but we're playing one of the best teams in Europe. I'm not overly disappointed with our performance so far but it still has the potential to turn really ugly very quickly too.

Daniel Hughes: To be honest realistically it was always going to be a long night for us against Bayern.

Here comes Kingsley Coman again but this time Mikael Lustig thwarts the livewire winger with a perfectly timed tackle in the box.
