The Ibrox captain's errors led to Rangers conceding goals in Switzerland.
Steven Gerrard's men took the lead in Switzerland thanks to a fine Alfredo Morelos finish in the first half.
However, after the break, the home side were far more aggressive with possession and managed to capitalise on an awful Tavernier error to equalise.
With the captain losing possession on the right flank, the Gers defence failed to deal with an advancing Ulisses Garcia, who crossed the ball in for Roger Assale to prod home.
Tavernier again appeared to be at fault for the Swiss side's dramatic late winner in a 2-1 result.
It's not the first time in his Rangers career that the Ibrox stalwart has been far too casual and allowed the opposition to find their way to goal.
In fact, for some supporters, it's happening with alarming regularity.
Given he's one of the first names on the team sheet under Gerrard, he needs to show far more composure on these occasions and stand up when counted.
On a night that should have resulted in a win or a draw, Rangers head home with nothing to show for their efforts.
These fans were left fuming, taking to Twitter to share their thoughts on his contribution...
The game so far has been typical Rangers, Morelos scored doing Morelos things and we concede because Tavernier does Tavernier things— DandyInTheGhetto (@Ml19dy76) October 3, 2019
Shocking defending. All started from Tavernier letting his man run right by him— ᒪᎥᗩᗰ (@LiamWATP) October 3, 2019
Rotten Tavernier— Wullie Bethel (@WullieBethel) October 3, 2019
Shocking by Tavernier. Why try and nutmeg one of their players on the edge of your own box?!— Scott Middler (@scott_middler) October 3, 2019
Tavernier needs a telling off— McGhee (@mcghee1984) October 3, 2019
Tavernier’s defending is completely non existent.— Tel-Aviv Loyal RSC (@telavivrangers) October 3, 2019
When his forward play is poor, as it is tonight - he is an empty shirt.
Been less than five minutes and Young Boys have already equalised. Really poor defending. Don't know what Tavernier is doing. Gifting them a tap in #Rangers— WATP.com (@WATP_com) October 3, 2019
I think Tavernier spends all his time pointing at players.... Instead of doing his job— Nacho Man (@nachoman18721) October 3, 2019
Tavernier has been a disgrace tonight— JC (@Jameyc11) October 3, 2019
