Celtic are piling on the pressure as Tom Rogic tries to weave his way through the ranks of Hearts defenders. The ball breaks to Kyogo Furuhashi and it looks like Rogic gets in the way of his team-mate's shot.

Celtic forward Kyogo Furuhashi cuts in from the left and takes aim for the opposite corner of the net with a low shot. Craig Gordon gets a hand to it as he comes out to narrow the angle.

Hibs threaten first in the second half as Josh Doig's cross is met by Kevin Nisbet but the Scotland international can't keep his effort down.

Celtic are stretching Hearts already as two crosses in quick succession from Anthony Ralston and David Turnbull cause consternation for the visitors.

Stephen Kingsley makes a great sliding block from the latter to deny Odsonne Edouard inside the six yard box.

Away we go at Celtic Park as the action resumes at Gayfield and Easter Road.

There are still three places up for grabs in the last eight of the Scottish League Cup.

Celtic manager Ange Postecoglou expects a "different game" to his side's 2-1 league defeat at Tynecastle.

"Cup ties have an edge to them," he tells BBC Sportsound. "Especially at the start I expect the pace to be pretty hot, which is ideal.

"We've had some promising performances but still have a long way to go. We have an opportunity today to improve our football."

Postecoglou is hopeful of adding further new signings imminently, and explains the absence of Ryan Christie.

"Ryan got a knock the other night and pulled up sore. It's best for us to leave him out today."

Hearts manager Robbie Neilson tells BBC Sportsound: "We had a fantastic result against Celtic at Tynecastle with our fans behind us, but coming to Glasgow is a different beast. We have to show we can win here.

"We planned to start Armand Gnaldullet today, but he has a family issue and misses out. Josh Ginnelly had a bug during the week and isn't ready to start.

"We come here with confidence. We want to do well in the cups, but this will be our biggest challenge in the last six months."

Three days ago, St Johnstone were facing Turkish giants Galatasaray. Now they're chasing a game against Arbroath at Gayfield.

Life comes at you fast.

Jon Nouble's close-range strike has Dick Campbell's team ahead against the cup holders.

The home side have had most of the ball but the best chances have fallen to Kilmarnock, with Scott Robinson denied by Matt Macey when clean through and Liam Polworth thundering a shot against the underside of the crossbar.

Two chances for Kevin Nisbet to try and get Hibs in front.

First, he creates space in the Kilmarnock box and forces goalkeeper Sam Walker to palm a shot away. Moments later, the Scotland striker glances a header wide.

The cup holders are pressing hard to get back on level terms.

Callum Hendry and Stevie May both try their luck but they can't force the ball into the net.

Hearts have made a fantastic start to the season, with six successive victories, including taking the scalp of Celtic on day one of the Premiership campaign.

This promises to be their sternest test yet though as Celtic begin to hit their stride under Ange Postecoglou.

Since that 2-1 loss at Tynecastle, Celtic have fired seven goals past Jablonec in Europa League qualifying over two legs and demolished Dundee 6-0.

The visitors are inches away from taking the lead at Easter Road as Liam Polworth's rocket from 25 yards leaves the crossbar shuddering and the Hibs defence scramble the ball away as it drops down on the line.

Aberdeen ended the game with nine men after late injuries to Jonny Hayes and Ryan Hedges.

Manager Stephen Glass says it's too early to tell if they are doubts for Thursday's visit to Qarabag but is confident he has players that can step in.
