Tottenham Hotspur right-back faces a huge test against Inter.
Tottenham's decision to leave Kieran Trippier behind for tonight's match with Inter Milan has raised a few concerns.
To look at it positively, it is the chance defender Serge Aurier has been waiting for.
Tottenham spend £24 million on the Ivory Coast international last summer and he has so far been unable to hold down a regular place in the team.
There's no shame in this, with Trippier excellent, but some of Aurier's performances have not been up to scratch either, not helping his cause.
Tonight's game with Inter Milan is the chance Aurier has been waiting for to prove himself.
It could go the wrong way, and Aurier could end up confirming the reservations Spurs fans have about him.
He faces a difficult test, likely to come up against Croatia World Cup hero Ivan Perisic.
Perisic is a world class attacker and it is a tough test for Aurier to take on.
If he can pass it with flying colours, this could be a turning point in his Tottenham career, for the better.
