Lazaar has moved to Hillsborough on a half-season loan deal, alongside his Newcastle teammate, the winger Rolando Aarons, having failed to break into Rafa Benitez's plans.
Though born in the Moroccan city, Casablanca, the 27-year-old spent much of his life in Italy, and was in Varese's youth ranks when Carbone was manager there in 2011.
Responding to a post on Sheffield Wednesday's official Instagram page yesterday evening, Carbone wrote: "I'm really happy for him [Lazaar] that he came to play with the blue-white shirt. [He] is [a] great player and fantastic person too."
And Lazaar replied: "[M]ister[.] Thank you for everything."
Carbone later expanded on his initial message on Twitter, posting: "So happy for you my boy, I am sure you will display all your potential!
So happy for you my boy, I am sure you will display all your potential!— BENITO CARBONE (@carbobenny10) 1 February 2019
You are now at my club @swfc , the fans will love you so much. I am convinced that you'll help the team make it back to where it belongs: The Premier League! Good luck Achraf and come on Owls! https://t.co/Uc8F9oBKZr
Carbone, now 47, was idolised by the Sheffield Wednesday fanbase during his three years at Hillsborough in the late 1990s, when he scored 25 goals in 96 games - including one against Newcastle.
However, his acrimonious departure to Aston Villa left a sour taste in the mouths of many Owls supporters.
Wednesday also signed the right-back, Dominic Iorfa, for an undisclosed fee from Wolverhampton Wanderers ahead of yesterday's deadline.
Newcastle fans - will Lazaar be a good addition for Sheffield Wednesday?
