Celtic could only draw in their latest league fixture but how did the summer signing get on?
Celtic saw their 100 per league start ended with a 1-1 draw at home to St Johnstone on Saturday.
The visitors took the lead in the 39th minute when Steven MacLean found the net and Celtic had to wait until 11 minutes from time to find the eqauliser, with substitute Callum McGregor rescuing a point for Brendan Rodgers' side.
Prior to this match Celtic had won three from three, scoring 10 goals in the process while also qualifying for the group stage of the Champions League with relative ease.
However those efforts could have been their undoing on Saturday, as so much football in quick succession enabled St Johnstone to take advantage of a tired-looking Celtic side.
One player who was not at his best was summer signing Olivier Ntcham, who only made it until half time at the weekend.
The 21-year-old moved to Celtic from Manchester City during the current transfer window and he has featured regularly both domestically and in Europe since that switch.
On his day he is a superb player, but Rodgers opted to hook him at the break, replacing the Frenchman with Stuart Armstrong and ultimately reaping the reward.
After the match we took to Twitter to see what Celtic fans thought of Ntcham's latest performance and you can read a selection of what we found below:
Would like to see Ntcham powering through, making more direct attack on back four runs.— Prof Patrick McGhee (@ProfMcGhee) August 27, 2017
We're short of options wide but I'd have rested Ntcham (who was magic v Astana) and played Callum. I think Ralston has 'it' - like him a lot— Bloke109 (@thebloke109) August 26, 2017
Don't know if you were there but Ntcham did not help matters - didn't make himself available for pass - looked exhausted— enattendanthector (@c67cb11f14b0422) August 26, 2017
We lost vision & composure the day when Ntcham went aff. Changed the game a wee bit!— Ryan (@IIIRFIII) August 26, 2017
Unlucky not 2 win today after a rotten 1st half. McGregor + Armstrong need a run in the team. Ntcham was poor. Happy tho after Astana trip.— Brendon (@harryhillmcgill) August 26, 2017
Ntcham wasn't the greatest but kept sweeping up mistakes made by others— Reece. (@_RH67) August 26, 2017
