Odsonne Edouard and an own goal from Richard Tait gave Celtic a 2-0 win over Motherwell to retain top place in the SPFL going into the final international break of the year.
Jeremie Frimpong and Olivier Ntcham came in for Hatem Abd Elhamed and Ryan Christie as Neil Lennon freshened up the side that had beaten Lazio three days earlier.
Motherwell were hoping to return to third place with a win but found themselves on the back foot from the first whistle with Deccy Gallagher standing between Celtic and an early opener.
In the 19th minute Edouard opened the scoring when he latched on to an interception from Gallagher and netted from 15 yards out.
Celtic should have increased their lead before the break but had to wait until the 54th minute to extend their lead when Tait was panicked in to heading into his own net from a Jonny Hayes cross.
Christie replaced Forrest midway through the second half as Lennon gave his internationalists a little respite knowing that when his side had racked up their seventh successive win across three competitions.
