BBC Scotland summariser at Celtic Park

Alloa carve out their first real chance with Greig Spence firing in from distance, but Craig Gordon parries away.

Terrific block by Neil Parry to deny Moussa Dembele after the Celtic striker had turned Mikael Lustig's cut-back towards goal.

Celtic left-back Kieran Tierney is becoming a real goal threat and he shifts on to his right before firing straight into the arms of goalkeeper Neil Parry.

Alloa right-back Scott Taggart is tad lucky to escape without a yellow card as he body-checks Kieran Tierney as Celtic dominate possession and pin the visitors back against the edge of their penalty box.

Jack Ross's Alloa have started well this season, winning 11 of their 12 games and leading League One. However, it would be a major surprise if the Wasps buzz past Celtic to reach their first-ever League Cup semi-final.

Rangers last night exposed the gap between the Premiership and the second tier with a 5-0 win over Championship leaders Queen of the South and they and Greenock Morton await in the semi-finals.

Mikael Lustig lifts a cross towards the back post where Celtic's Moussa Dembele heads off target.

The third quarter-final in this season's Scottish League Cup gets going.

Good old-fashioned numbers 1-11 on the shirts of the Alloa players tonight.

Alloa Athletic manager Jack Ross on BBC Radio Scotland: "We have a relatively small squad. We will tweak the system, but by and large it is the same people involved. 

"I believed we would do well and be competitive this season, but I would be lying if I said I expected to start with 10 wins. 

"My players have smashed records right, left and centre and, although this is the hardest task we could have had, there is no point in us coming here if we are not out to win.

"I am desperate for them to go out and show how good they are as players tonight."

"Dorus de Vries warming up Craig Gordon ahead of Alloa match. Gordon back in starting line-up."

Celtic manager Brendan Rodgers on BBC Radio Scotland: "This is a competition that we would like to do well in. We respect Alloa, we've done all our homework on them. We're playing at home, we love playing here and our objective is to get into the semi-final.

"I don't see us as having a number one [goalkeeper]. I've got really good goalkeepers. Craig [Gordon] has been brilliant. He's worked even harder at his game. When the chances come for him to play, he'll be ready."
