The Scotland international kicked off an exodus from Tynecastle to Ibrox over the summer after leaving the Jambos for the club he supported as a boy, with manager Derek McInnes and Cammy Devlin later following him west.

Shankland is currently sidelined with a serious hamstring injury but made sure he was in attendance for the Premiership clash.

And the 31-year-old received a hostile reception from the home support as he made his way to a seat behind the Rangers dugout.

Speaking on Sky Sports commentary, Celtic icon Chris Sutton said: "They're all booing him after the service he gave to Hearts?"

Shankland made 171 appearances for Hearts, scoring 88 goals during a prolific four-year spell in Edinburgh.
