Goals from Kyogo Furuhashi and Jota ensured the league leaders restored their six-point advantage over Rangers at the top of the table ahead of next week’s potentially decisive Old Firm fixture at Celtic Park.
Rangers had reduced the gap with a 3-1 win over Motherwell on Saturday – despite having Leon Balogun sent off in the first-half – but Celtic were always in control in the Highlands after taking a 12th minute lead when Kyogo headed home Jota’s cross.
The Portuguese winger then got his name on the scoresheet with three minutes remaining to seal the victory.
Here is how the Celtic players rated out of 10:

4. Cameron Carter-Vickers - 8
