Stefan Johansen, Leigh Griffiths and Anthony Stokes grabbed the goals yesterday as Celtic swept away St Mirren to move within four points of clinching the SPL title.
The championship could be clinched at Firhill on Wednesday night if Celtic win against Partick Thistle and Aberdeen fail to beat Ross County at the same time.
If the Dons win the party plan will be relocated across the city for Saturday when Celtic host Ross County- the team that they started the season against.
Yesterday it was business as usual for the hoops with the match following a similar pattern to the 3-0 win away to Kilmarnock eight days earlier when Kris Commons helped himself to a hat-trick.
The goalscoring midfielder was a little off the boil yesterday but stepping upto the mark was Johansen with Liam Henderson making a favourable impact in his home debut.
Johansen opened the scoring shortly before half time with a well placed header from a Griffiths cross that killed off any hopes St Mirren had of taking anything from their trip to Glasgow.
Celtic stepped up the pace after the break and could easily have finished the day with five or six goals as news came through that Aberdeen had gone in front at home to Kilmarnock.
Griffiths and Stokes both added to their tally as their partnership continues to develop carrying the threat of looking like scoring every time that they take the pitch.
At the back Fraser Forster added another clean sheet with the only downside being bookings for Virgil van Dijk and Charlie Mulgrew as referee Stephen Finnie demonstrated the same level of competence as his two flag happy assistants.
