Aurier started at right-back for Spurs in their Champions League match last night, but the Ivorian defender was lucky to stay on the field.
With Tottenham winning comfortably, Aurier stamped into a challenge on an APOEL attacker.
And Jenas feels that Aurier is simply too inconsistent within matches.
The former Tottenham midfielder said: “He’s a weird one. He does things in a game which are brilliant, but he has this other side to his game where he does mad things. He’s becoming a liability.”
Aurier had set up Tottenham’s first goal of the night, when he put in a fine cross for Fernando Llorente.
The former PSG man has shown flashes of brilliance throughout his Tottenham career to date, but he has also made some high profile errors.
Aurier is in competition with Kieran Trippier for a place at right-back, and the England international does appear to be the more consistent option.
Spurs’ win over APOEL has meant that they have picked up more points than any other team in the Champions League group stage, after going unbeaten in all their European matches to date.
Tottenham are next in action at the weekend, when they take on Stoke City at Wembley.
