After breaking into the first team, he seemed set for stardom in Amsterdam before a fallout with then head coach Petr Bosz paved the way for his switch to Lille in January 2017.
El Ghazi scored five times in 39 Ligue 1 appearances, but was not part of Lille boss Christophe Galtier's plans for the current campaign.
"Aston Villa is delighted to announce the signing of Anwar El Ghazi from Lille on a season-long loan," the club signalled on their official website.
"Capped at senior international level by the Netherlands, El Ghazi has been with Lille since January 2017.
First of all I would like to thank all of Lille’s fans for everything. You will forever remain in my heart and you never know what the future will bring. Right now I am really happy with this new challenge and I am looking forward to meeting all Aston Villa fans. pic.twitter.com/FEvVbgPtFw— Anwar El Ghazi (@AElGhazi7) August 22, 2018
Also speaking to the website, El Ghazi stated: “I am thrilled to join a football club of the size of Aston Villa.
“I visited Villa Park late last night after flying in from Holland and it gave me goosebumps.
“I can’t wait to get out there and experience it for real and play in front of such passionate fans.”
The Netherlands international will hope to aid Steve Bruce's bid to return Villa to the Premier League after last season's play-off final loss to Fulham.
