Souchax exploited Auxerre's injury woes, by grabbing all three points at Stade l'Abbé-Deschamps against a stubborn hosts in the form of AJA.
The visitors were quick to get a head start as they made inroads into AJA's defence, with Olivier Sorin doing his best to keep the visitors from scoring.
On the other hand, Auxerre used their possession in a better manner with particularly Valter Birsa and Roy Contout coming close to open up the hosts Ligue 1 goal-account.
With Marvin Martin's opening being thwarted by AJA's rearguard, AJA's defensive personnel must have sighed a breather for relief.
However, Vaclav Sverkos made full use of a good play between Vincent Nogueira and Ivan Stevanovic on the right flank as his angled shot would find itself at the back of the net.
But Auxerre made up for a disappointing first half by attacking the visitors end, with much fluidity as they made double substitutions in the second half.
Kamel Chafni saw his effort disallowed for an offside and substitute Charlie Davies was the closest to level the scores, but it wasn't going to be AJA's day.
Souchax would be very pleased, after their average second half performance, to have picked up all points from this crucial opening tie.
