Quote MessageIt's astonishing the lack of awareness from the Celtic defenders tonight. The goals they've conceded are a complete disgrace. No one is taking responsibility.
Rangers v Benfica (20:00)
Steven Gerrard makes two changes from the 4-0 win against Aberdeen at the weekend, and they both come in central midfield.
Ryan Jack and Joe Aribo both drop out of the squad altogether, and into the starting line-up come Steven Davis and Glen Kamara.
It's a relatively inexperienced bench with Uefa rules on homegrown players meaning the likes of Jermain Defoe aren't registered.

Quote MessageCeltic are uncharacteristically soft this season. When you continue to give opportunities to the opposition you will never win on a consistent basis. They're fortunate they're not losing by more here.
Celtic are in trouble here, they are a mess at the back.
Odsonne Edouard fired the visitors in front with a fantastic goal but that good work has been undone by uncertain defending.
Sparta have been lively but both goals were gifts.

Quote MessageThat's a guilt edged chance. I can't believe he's missed that. But again nobody is picking him up and he's in the six yard box.
Sparta Prague 2-1 Celtic
A huge let-off for Celtic as Ladislav Krejci crashes a free header against the post from a free kick and Scott Bain is in the right place to gather the rebound.
Krejci was only six yards out and really should be scoring there.

Quote MessageCeltic haven't been able to gain control of this game. Other than the goal their attacking players haven't featured at all. They need to get their foot on the ball.

Celtic look a bit sorry for themselves here as Sparta continue to buzz around with menace.

Quote MessageI don't think Jullien realises Julis is there. Elhamed should be the one tucking in and covering the run. Then everyone hesitates. An absolute horror show.
Lukas Julis
More calamitous defending from Celtic allows the hosts to move in front.
A low ball in from the right is allowed to travel right through the penalty area and Scott Bain doesn't come to claim it.
Lukas Julis looks like he might be offside as he races in to prod the ball home from close range but Celtic really should have dealt with the cross.
Sparta Prague 1-1 Celtic
It's a wide open game now as Callum McGregor gets to the bye-line on the left to ping in a delivery. Odsonne Edouard is winding up for the volley but a defender gets a slight touch to nudge the ball to safety.
Sparta Prague 1-1 Celtic
A cross from Hatem Elhamed goes through a cluster of players inside the Sparta penalty area and breaks for Olivier Ntcham.
The Celtic midfielder has time to set himself for the shot but rushes it and the ball skews well wide.

Quote MessageI look at the Celtic defenders and I'm not sure there's a desire to defend. They should be fighting tooth and nail for a clean sheet but they don't seem bothered.

A hack at the heel of Diego Laxalt earns Andreas Vindheim the first booking of the evening.

Quote MessageCeltic don't deal with the first ball into the box. How many times has that been their Achilles heel? It's a poor header from Jullien straight down into the box and an easy finish
David Hancko
Celtic are caught short at a corner as Christopher Jullien fails to get any distance on a header and then Scott Brown gets in a fankle at the edge of the box, allowing a shot to come in. The effort is deflected into the path of David Hancko and the defender can't miss from right in front of goal.
Sparta Prague 0-1 Celtic
Sparta are pressing hard for an equaliser, with Christopher Jullien and Kristoffer Ajer busy heading away a series of crosses.
Sparta Prague 0-1 Celtic
Scott Bain has to work a little bit harder this time as he gets down to stop a shot from Lukas Julis.
