Arsenal have failed to win a trophy in eight years since the FA Cup in 2005. In the following seasons Wenger's only saving grace has been Champions League qualification.
Unlike other owners such as Chelsea's Roman Abramovich, the Arsenal board has been lenient with the Gunners manager and haven’t demanded instant results.
It could be argued that even though Abramovich's trigger finger is unfair to his managers, it does create an understanding that failure to win is not an option. Roberto Di Matteo was only in the job for six months and won the Champions League, something Arsenal have so far failed do to.
Arsenal fans have been split in their judgement of Wenger, some believe the lack of trophies is not good enough for a club of Aresnal's stature but others are satisfied with constant Champions League football.
Tottenham have been pushing for the fourth spot and have come very close, if they beat their north London rivals to Champions League football the repercussions for Wenger could potentially be dire.
Wenger has achieved Champions League qualification for Arsenal for 15 consecutive years but for the last eight seasons he has come under scrutiny. Doubters question how long he can remain trophyless and still retain the Arsenal manager's job - surely there comes a time when enough is enough.
It can be argued Arsenal have been unlucky to not have won a trophy in this period, losing in three separate finals, two in the League Cup and one in the Champions League.
This season Arsenal look to be pushing harder than in previous years to for a trophy by claiming they intend to claim a marquee signing from their proposed £70 million war chest, despite failure to sign any of their targets so far.
In this transfer window they have also held onto their key players, something which Wenger has been criticised for failing to do in his recent reign. If he had kept players of the calibre of Cesc Fabregas and Robin van Persie, the Gunners would surely be firing on all fronts.
Something Wenger can be credited for is that he has created one of the best youth systems in Europe at Arsenal alongside managing a transition from Highbury to the Emirates.
There is no doubt that Arsene Wenger has achieved great things at Arsenal, however he cannot dine out on past glories for ever and as long as Arsenal remain trophy-less fans will continue to question how long he may remain at the Emirates.
