Neil Lennon’s side haven’t conceded a goal in their last four league games, with many Hoops supporters praising forward Leigh Griffiths on social media.
The 30-year-old kept his place in Lennon’s starting line up at Celtic Park after scoring against Hamilton on Boxing Day.
Ismaila Soro and David Turnbull both scored from long range in the opening 45, with Griffiths setting up strike partner Odsonne Edouard to seal the win with 15 minutes remaining.
The Scot played Edouard through with an excellent outside of the foot lobbed through ball, with the Frenchman dinking Benjamin Siegrist.
This is what these Hoops fans had to say about Griffiths, with many happy with his 77-minute display. One supporter labelled his late assist as ‘class’.
Twitter: The impact that Griffiths has on any Celtic side he enters into is absolutely unreal. (@danny_w1998)
