CELTIC booked a place in the Scottish Cup fifth round with a 3-0 win over Albion Rovers at the Excelsior Stadium this afternoon.
The triumph extended their unbeaten domestic run to 25 games and kept them on course for the Treble.
Scott Sinclair, with an remarkable dipping shot on the half-hour mark, and late second-half strikes from Moussa Demble, his 20th of the campaign, and Stuart Armstrong made certain there would be no sensations in Airdrie.
There were rare first team starts for Dedryck Boyata, Cristian Gamboa and Nir Bitton as Brendan Rodgers kept his line-up fresh and also looked towards the Premiership match against St Johnstone at Parkhead in midweek.
The return to action of Kieran Tierney – the teenage left-back who made his first start since the Betfred League Cup semi-final against Rangers in October – certainly injected quality into the visiting side.
The Scotland internation defender, who underwent ankle and shoulder surgery during his time out, came through the outing unscathed and set up the opening goal before being replaced in the 61st minute by Callum McGregor as a precaution.
Mikael Lustig, who last week signed a two year contract extension, took a minor knock and was replaced at the interval by Jozo Simunovic.
