Image source, BBC SportOh dear, Sparta are on for back-to-back 4-1 wins over Celtic as Scott Bain has another shocker.
The keeper comes charging out his area and is nowhere near Srdan Plavsic, who skips past him then dances away from Callum McGregor to roll the ball into an empty net.

Quote MessageIt's getting worse for Celtic. The pressure of 10 in a row is really telling. I still think Neil Lennon deserves the chance to change things but a few more results like this and who knows?

Celtic are just waiting for the final whistle to put them out of their misery.
Three minutes of stoppage time to endure.

Quote MessageOh my word... defensively again Celtic give the ball away in a critical area and then fail to deal with it. You just can't win games defending like this. It's fault after fault.

Another moment of uncertainty at the back for Celtic as Scott Bain and Christopher Jullien fail to communicate just outside the penalty area. The dithering keeper has his attempted pass blocked by livewire David Moberg-Karlsson but Bain is able to dive on the ball inside the area and retrieve the situation.

Patryk Klimala is on as Odsonne Edouard trudges off. The departing Celtic striker may be replaying that glaring second-half miss inside his head.
Lukas Julis
It's a sucker punch and Celtic are definitely heading for a premature exit now.
Hatem Elhamed is the blundering defender this time, with a weak header and then a mis-timed effort at an interception.
David Moberg-Karlsson motors away and dinks over the perfect cross for Lukas Julis to slam past Scott Bain.

Celtic are going out of the competition with two games to spare if stays like this.
They need to have a real go in these last 15 minutes.

Quote MessageIt looks as though Sparta are trying to sit back and hold on to what they have here. Despite the injury to their centre back they're sticking with the back five.

Quote MessageEdouard's taken by surprise that the defender has missed it. He even had time to take a touch there but it's such a weak shot. What a chance.

Olivier Ntcham does well to wriggle his way past a couple of opponents and slide a pass across the penalty area. It looks like a Sparta defender is going to intercept but he misses the ball altogether and Odsonne Edouard is all alone eight yards out.
The striker is falling back a bit and can only scuff a weak shot at the keeper.
What a chance!

As they press for an equaliser, Celtic are leaving some big gaps at the back. Kristoffer Ajer is absolutely skinned by David Moberg-Karlsson but the Sparta striker then runs into traffic and loses the ball.

Quote MessageCeltic are in control of the game. They're passing it well and will create opportunities with the players they've got. It's just breaking down at the last point so far.
Sparta Prague 2-1 Celtic
Kristoffer Ajer jinks away from Ladislav Krejci near the halfway line and the home player has a hack at his ankle to go in the ref's book.

Samu Castillejo has just given AC Milan the lead in Lille.
As it stands, the Serie A leaders are top of the section.

Quote MessageThat was Celtic's best bit of attacking play in this game so far. Lots of good build up and Christie just couldn't get the bend on the shot. Much better on that occasion though
Sparta Prague 2-1 Celtic
Much better from Celtic as they move the ball around with real vim and vigour. A neat passing move culminates with Ryan Christie flashing a curling shot wide of the far post.
Sparta Prague 2-1 Celtic
Ryan Christie is chopped down just outside the penalty area. Odsonne Edouard sizes up the free kick and gets it up and over the defensive wall.
Goalkeeper Florin Nita is at full stretch to push it away near the base of the post.
