James Forrest bagged a brace as Celtic beat Motherwell 4-0 at Parkhead on Saturday afternoon.
Joe Ledley and Ki Sung-Yueng also scored as Celtic climbed to within a point of Rangers, with the first Old Firm derby of the season taking place next weekend.
Some excellent passing led to Celtic's opener, with Gary Hooper dropping back to midfielder to release Anthony Stokes on the wing. The Irishman's low centre was converted by the onrushing Forrest for a deserved lead.
Stokes again provided the assist for Celtic's third, Joe Ledley controlling and converting from inside the box.
Ledley set up Ki for Celtic's third, the midfielder catching the shot perfectly with the outside of his right foot to power into the top corner, before Forrest's shot took a slight deflection before beating Randolph to round off the scoring on 74 minutes.
