00:00For the ninth time, it's actually a competition, Celtic have won their last five meetings with Rangers, going back to the 2010-11 final.
00:20There we go, semi-final record against one another in both major cup competitions, Celtic have won 10, Rangers 11.
00:30Tavernier targeting Suter, angles rise as well, Maeda, send it straight back to Tavernier but that's a loose one and Moore couldn't get there,
00:55Hitate has Osmond ahead of him, Osmond against Tavernier as he's still got something in the legs.
01:04Callum Osmond, let down by the Rangers captain.
01:08Celtic look to take that one quickly, I think maybe not from the right place though.
01:15I've got to say, Callum Osmond's looked bright, very direct and positive in his play, even then when he checks inside and you're thinking he's maybe just lost the momentum,
01:27he goes again, forcing James Tavernier into having to defend, never been able to take a moment's breath and I think he's been positive, he's had a couple of opportunities.
01:42Oh, he wasn't given any opportunities before Martin O'Neill came in.
01:51Adam Osmond arriving from Fulham where he was nominated for Premier League Player of the Year, that's a cross from Hitate.
02:01Hitate, the flag does go up, Cornelius sliding in to make that one clear.
02:08Hitate goes down under Alan Schaldinger to make the most of that.
02:11Like a tombstone.
02:14You can see there, good call from the linesman.
02:29There's Trusty again, he's been very good.
02:34Winning a lot in the air but just in general those duels when he's been asked to question from anybody.
02:41Rangers jersey, he's done pretty well, Austin trusty.
02:44Come on, come on, come on!
02:48Come on, James, here you are now!
02:53Come on, back, back!
02:56Ralston, Osmond's touch just sent it straight to Rockwell but he won it back,
03:02made it to Hitate, there's Cornelius and that was important because Forrest was away.
03:06Engels, Forrest, break comes to McGregor the extra man, making a difference now.
03:15Kieran Tierney and sliding in is Osmond!
03:19Is that the moment that finally separates these two?
03:26What a moment for Callum Osmond!
03:31One he will remember for the rest of his days.
03:36The 19-year-old slides in at the Celtic end at Hampden Park to put his side 3-1 up in the Premier Sports Cup semi-finals against the great rivals Rangers.
03:50But they're just utilising the space on the sides.
03:53Good positive play from Kieran Tierney, you can see he's onside, he's bright, he's alert.
03:59He gets himself in between the sticks and he puts it in the back of the net.
04:03That's a good striker's goal, Rory.
04:08Positive play from Tierney, he fires it across the face of the goal and it needed him to put it in because
04:14Tierney's strike is not on target, it's going across.
04:18And that just seems to get that little bit of a breathing space that Celtic have been desperately chasing all afternoon.
04:32Dyson Maeda's job is done.
04:38The Rangers fans, some of them, have lost belief.
04:50They don't see a way back.
04:52Celtic have their two-goal cushion.
04:55Baliquisha comes on to smiles because Callum Osmond has given them the 3-1 lead.
05:04He scored 18 goals for the Fulham under-21s in Premier League 2 last season.
05:12That's his first for Celtic.
05:14He challenges there and his over-exuberance will get him a yellow card.
