It looks like the Argentine will make his debut for the club at The Emirates on Saturday.
One of the biggest transfer sagas of the summer was the interest in Argentine Gonzalo Higuain - after he made his intentions clear to leave Real Madrid.
The potent striker was subsequently linked with plenty of outfits - with Juventus and Arsenal playing cat and mouse for a couple of months over whether to snap up the player.
It quickly became apparent that Juve could not afford him, leaving Arsenal the overwhelming favourites to snap up the striker.
And if the papers were correct, then Higuain conducted around six or seven medicals with the Gunners that. in the end, proved to be phantom.
As Arsenall dilly-daddled over a move for the player, the same cannot be said about Napoli.
After selling Edinson Cavani for the price of a small island, they announced their interest in the player - and snapped him up a week later.
In terms of demonstrating how to get your man in the transfer market - Napoli president Aurelio de Laurentiis should write a text-book.
But, as Arsenal’s pursuit of dream signing Luis Suarez continues to look increasingly futile, they may be given the unfortunate chance to realise the opportunity they missed out on this weekend.
Have you ever been in a relationship with someone, ended it, then seen them a few weeks later and thought - ‘What have I done?’
Well on Saturday, Arsenal might just experience that feeling.
Opportunities to sign players the calibre of Higuain, with the ease in which Napoli did, only come along once in a blue moon. The Gunners simply let it pass them by - and when they face Napoli in the Emirates Cup at 16:20 tomorrow that might just be highlighted to them.
If Higuain was to score, something he does tend to do, it would be a real sucker punch for Arsenal.
It would be his first goal for the club and, it would be on debut at the home of the team who could have signed him.
Enough to turn the faces of the Arsenal hierarchy as red as their kit.
