In recent years, Arsenal's transfer dealings have included many more hits than misses, with the likes of Martin Odegaard, Ben White and Aaron Ramsdale proving to be worth every penny the club paid for them.
Of course, there have still been odd misses here and there, such as Nicolas Pepe and potentially Kai Havertz, if he doesn't improve towards the backend of the campaign, but the trend is undeniably positive for the Gunners.
However, there is one signing the club have made in the post-Wenger era that remains unmatched in terms of value for money, and has a shout for being one of the best value signings in the entire Premier League over the last five years.
The player in question has seen his value skyrocket 1333% since moving to N5, has established himself as one of the club's most important players, and was signed by Unai Emery.
Gabriel Martinelli's valuation at Ituano
The player in question is obviously Brazilian wonderkid Gabriel Martinelli, who Arsenal signed for just £6m from Brazilian fourth-tier outfit Ituano Futebol Clube in the summer of 2019.
At the time, he was a relative unknown to football fans in England but had been making a name for himself in his homeland and left Ituano with six goals and three assists to his name.
His form in Brazil also caught the national set-up's eye, and he was invited to a May training camp with the full squad before his move to Arsenal was announced.
There was clearly an element of excitement around the tricky forward early on, but his full potential wouldn't be clear until he started playing regularly for Arsenal.

Ultimately, Martinelli's move to Arsenal has been an unequivocal success both from a football perspective and a business one and if he can help fire the Gunners to a league title, his value might soar yet higher.
