It's fair to say that Mesut Ozil's £42 million transfer deadline day switch to Arsenal caused a stir in the football world.
With Emirates boss Arsene Wenger seemingly reluctant to 'splash the cash' in years gone by, the French tactician's sudden change of heart shocked many.
That said, the opportunity to sign a genuine world class talent doesn't come around too often, so in that respect you could argue the Ozil deal was a no-brainer for the powers that be in the red half of north London.
And while the signing appears to have paid instant dividends for Arsenal, outsiders questioned Ozil's ambition in signing for a team more accustomed to challenging for a top four finish, rather than major honours.
After all, Ozil - dubbed the 'King of the Assists' for his ability to lay on goalscoring opportunities for his teammates - has fantastic pedigree and is widely considered to be the best attacking playmaker in world football.
At the age of just 24-years-old, Ozil could yet go on to become one of the greatest of his generation - so why Arsenal?
Speaking to Arsenal's official website having signed for the Emirates outfit, Ozil highlighted the fact that Wenger was a major factor in his decision, before suggesting the club's ambition was "very important".
However, in his first interview as a Gunner, Ozil's interview was as telling as it was positive - read between the lines, and it's clear that Ozil may well be using Arsenal as a stepping stone to greater things.
Arsenal's impressive start to the season has been as surprising as it has emphatic. Top of the Premier League and their respective Champions League group, things look rosy for the Gunners at this early stage of the campaign.
Ozil has been instrumental and key to their success, but if he continues to impress then don't be surprised if Arsenal are forced to fend off interest in their most prized asset.
And while it's inevitable that Wenger & Co. will send any faxes straight to the shredder, could Ozil's head be turned?
Things didn't work out for him at Real Madrid, granted. But if Arsenal fail to maintain their impressive start and if they were to extend their eight-year trophy drought to nine, dare I say ten years, then Ozil will re-consider his Emirates future.
For Ozil - and Arsenal - to progress, the success of both player and club must go hand-in-hand. If the Gunners do not mount a serious title challenge or end their trophy-less run over the next two or three years, then they risk losing Ozil to a rival.
Ozil himself has been unequivocal in his desire to win. Speaking to Arsenal.com, he said: "Arsenal haven’t been so successful but we want to become more successful. We want to win trophies."
For Arsenal and Wenger, the message is clear.
The German international will not be content with an empty trophy cabinet. Having been convinced by Arsenal's ambition, the north London club must fulfil their part of the deal for this relationship to continue into the long-term.
Having exceeded expectations and landed a genuine world class player, Arsenal must now continue their early season promise to keep Ozil for the foreseeable future - failure to do so could be disastrous.
