Ntcham was part of the Celtic side which lost 5-0 against PSG on Tuesday.
Olivier Ntcham has enjoyed a solid start to his Celtic career, scoring two goals and assisting another in his first 10 outings from central midfield.
However, his latest display has left much to be desired in the eyes of many Bhoys supporters.
Ntcham was part of the Celtic side comfortably beaten, five-goals-to-nil, by Paris Saint-Germain in the two sides' Champions League group stage opener at Parkhead on Tuesday.
With the visitors boasting a strike trio worth close to £500 million combined, it is perhaps no surprise that Brendan Rodgers' men struggled against the Group B second seeds.
But Ntcham is deemed to have fared worse than most - against his hometown team, no less, and that which his family continues to support.
Suspicious? At least one Celtic fan seems to think so. Here's what they're saying about the £4.5 million Frenchman.

Ntcham's not at the races tonight. Poorest 45 in a Celtic jersey that's for sure.— Brian (@Stoneysnapper) 12 September 2017
He's got some tough competition I grant you, but Ntcham has been pish tonight— Diamond (@DiamondBurkey) 12 September 2017
Ntcham has looked like a PSG fan tonight. Someone had to say it.— Ewan (@CockneyRhebel) 12 September 2017
Thinking Celtic should have played Ntcham last night.— .Ah Magners (@Aelred82) 13 September 2017
Ntcham and Celtic can make amends for their opening day disaster when the Bhoys travel across the channel to Anderlecht in a fortnight's time, with a double header against heavyweights Bayern Munich scheduled for next month.
Celtic fans - what did you make of Ntcham's performance?
