In a recent Q&A with Arsenal fans at the Emirates Stadium, Arsene Wenger highlighted the signing of Patrick Vieira as the key decision during his reign at the club.
As the French international was his first addition as manager of the Gunners, it's easy to see the significance of the signing from AC Milan.
However, a large contingent of fans in north London would argue that his most important signing was compatriot Thierry Henry - the club's all-time leading scorer and spearhead of the attack during a glorious period for the club in the Barclays Premier League.
Now immortalised in bronze outside the ground, it's inside where the fans would like to see the player most - and still could if reports are to be believed.
"It has to come through my brain at some stage but I haven't been concrete on the case," said Wenger during a press conference on Friday.
After being pushed by journalists on the matter, it certainly will have become clear to Wenger that it's a topic being hotly debated between the media in England and America.
Most recent suggestions, in The Times yesterday, claimed Wenger was now considering a one-month loan deal for his compatriot - how times quickly change. The deal would make him available for matches against Fulham, Swansea City, Manchester United and Bolton Wanderers in January.
Yes, United are in the list of possible opponents, and yes, the move would also coincide with the African Cup of Nations, when both Gervinho and Marouane Chamakh are away with their respective international teams.
It's true that Henry is not the player he was at Highbury, breaking teams apart with his pace during the 'invincibles' era.
He does still have an eye for goal however, with 14 in last season's MLS campaign showing his finishing is still up to scratch.
The most obvious point to mention is - what do Arsenal have to lose?
Apart from money, the answer is nothing. Henry would serve as back-up for Robin Van Persie, and whilst questions over his ability to perform at the highest level are up for debate, there is little to suggest that Park Chu-Young is a better option.
For the New York Red Bulls, injury is the major concern, which is where the money problem comes for the Gunners. Insurance, which stopped David Beckham from joining Spurs last January, could make it a big-money move for just 31 days of service.
There is little doubt that Henry would be unwilling to put the Arsenal shirt on once again - his love for the club is unquestioned and loyalty to Wenger evident from their eight years together previously.
Everton's successful move for Landon Donovan shows the MLS-Barclays Premier League divide can be broken, whilst the Toffees manager also made a relatively tongue-in-cheek offer for the 34-year-old to move to Goodison Park too.
Whilst a move to Merseyside was never on the cards, it shows that clubs would be more than happy to take on the legend, and Wenger is under no illusions that the player could still cut the mustard at the highest level. When asked that very question, the reply was simple. Yes.
So, Mr Wenger, make it happen.
