A clever strike by Shaun Maloney and a controversial goal from Gary Caldwell gave Celtic a comfortable 2-0 win over 10-man Hearts at Tynecastle and took them back top of Clydesdale Bank Premier League.
Rangers had gone top on goal difference with a 5-0 home win over Inverness Caledonian Thistle on Saturday but the champions stormed back in impressive fashion in Gorgie.
After just seven minutes Maloney volleyed the ball back over the head of Janos Balogh after the Jambos keeper had punched clear an Andreas Hinkel free-kick before Caldwell appeared to use a hand in doubling the visitors' lead from close range.
The champions could even afford to miss a penalty six minutes after the break after Marius Zaliukas had been shown a straight red for a 'last-man' foul on Scott McDonald, Paul Hartley sending his spot-kick wide of the target.
Although there was some dubiety surrounding Caldwell's goal and even allowing for the extra-man advantage they enjoyed for most of the second half, this was as convincing a victory as the Parkhead side have recorded in Gorgie for many a year.
The win will stand them in good stead, if anything can, for their Champions League Group E rematch with Manchester United at Parkhead on Wednesday.
