SPL review:Gary Hooper's double helped Celtic go 17 points clear of administration-hit Rangers at the top of the Clydesdale Bank Premier League as Neil Lennon's men hammered Hibernian 5-0 at Easter Road.
Goals from Anthony Stokes and the former Scunthorpe striker gave the impressive visitors a commanding interval lead over Pat Fenlon's struggling side.
Hoops defender Charlie Mulgrew fired in a free-kick just after the break and Hooper grabbed his second before substitute Ki Sung-yueng, on for Victor Wanyama, made it five to extend the Parkhead side's winning domestic run to 18 games.
Aberdeenextended their unbeaten run to 10 matches with a goalless draw against St Johnstone.
Fraser Fyvie headed wide from a Ryan Jack cross in the best chance of the first half, while Francisco Sandaza fired over from the edge of the area after 58 minutes when he really should have netted his 15th goal of the season.
Apart from that, chances were few and far between during a fairly low-key encounter at Pittodrie with a share of the spoils probably a fair result.
