The Gunners have been riding a wave of positivity for some time now, having not only ended their nine-year trophy drought, but also snapped up three new players in Barcelona's Alexis Sanchez, Newcastle United's Mathieu Debuchy and Nice goalkeeper David Ospina.
Yet one of the situations threatening to drag the mood down at the Emirates Stadium surrounds England international Wilshere. The 22-year-old has once again been pictured smoking during a holiday in Las Vegas, which has obviously caused a storm over his commitment to the Arsenal cause.
Having seen his development stall somewhat following a number of niggling injuries, Wilshere had the opportunity to stake a claim for a first team position this summer - but the smoking has reared its head again, leading to an apology from Wilshere today.
"The smoking? Of course I regret it," he said. "I’ve been seen before doing it. I said then I made a mistake and I have made a mistake again.People make mistakes. I’m young and I’ll learn from it. I realise the consequences it has and the effect on kids growing up. I have kids myself and I don’t want them growing up to think their dad smokes and it’s OK for a footballer to smoke because it’s not. It’s unacceptable and I will accept the consequences and I will move on."
Manager Arsene Wenger is renowned for his insistence that his players should eat the right foods and keep themselves in peak physical condition at all times in order to remain at the top of their game. This isn't the first time Wilshere has been caught smoking, and Wenger will no doubt be disappointed to see that Wilshere hadn't learnt his lesson.
The next season could be crucial for Wilshere. With Aaron Ramsey proving himself to be one of Arsenal's key midfielders, the pressure is on Wilshere to perform. Getting himself in trouble with Wenger will certainly make that harder, and how many chances Wilshere now has under the Frenchman remains to be seen.
Another offence in the coming months would make it hard for Wenger and Arsenal to stand by him again. Whilst it's by no means the worst offence imaginable, a third time would bring his commitment to the cause in to serious question - and Wenger is unlikely to stand for it again.
