Celtic are 45 minutes away from a place in the Scottish League Cup final after taking a 2-0 lead in at half time against fierce rivals Rangers at Hampden Park.
Goals from Leigh Griffiths and Kris Commons have put the Bhoys firmly in control in the first Old Firm clash for nearly three years.
The game began at a frantic pace and it was Griffiths who gave Celtic the lead after 10 minutes when he met Stefan Johansen's cross with a fine header.
Griffiths was at it again minutes later, but this time he could only direct Mikael Lustig's delivery wide of the post.
Commons extended Celtic's advantage shortly after the half-hour mark when he latched onto a loose ball to hammer home from the edge of the box.
Vrigil van Dijk spurned a great chance to make it 3-0 before Steve Simonsen denied Johansen by saving with his legs.
