The Arsenal legend has voiced his opinion on Twitter that the Dutchman was a more important signing than the French forward.
Indeed, Wright believes the Dutchman changed the club's 'DNA' and laid the foundations for the years of success that were to come under Arsene Wenger.
Thierry Henry, however, was a 'calculated gamble,' Wright argues, who wasn't as important to the club's fortunes despite going on to do so well.
The ex-Arsenal striker made his views clear when taking to Twitter and looked as though he wasn't prepared to hear any counterarguments!

As for their current forwards, the north London side don't have a centre-forward with quite the pedigree of an Henry or a Bergkamp but they do have a under-rated striker in Olivier Giroud and a superstar in Alexis Sanchez who may well have compared to Henry or the Dutchman in their day.
The Gunners face Swansea City on Monday night and will be wary of their bad experience against the Swans in Wales earlier this season. Arsene Wenger's men took the lead at the Liberty Stadium but were pegged back and ended up losing 2-1.
It is a different Arsenal side now, however, especially at the Emirates.
