Kevin Thomson believes both Celtic and Rangers face renewed pressure after the title lead swapped, as he told his former side to "wake up".
The second derby clash of the season saw Ange Postecoglou 's side take a dominant 3-0 win to go top of the Premiership by a point.
Despite the emphatic win there are still 14 games remaining though, and Thomson knows first hand that both leading and chasing bring their own pressures.
