The on-loan Sporting Lisbon winger grew up with Diagouraga in Paris.
Leeds United summer signing Hadi Sacko has told the club's official website of how his longstanding relationship with new teammate Toumani Diagouraga has "made it easier" for him to settle into life at Elland Road.
Sacko joined the Whites on a season-long loan deal from Sporting Lisbon last week, and made an immediate impact by scoring on his debut in the 2-1 friendly win over Shelbourne on Wednesday night.
The 22-year-old Frenchman has never played in England before in his career, dividing his time between France and Portugal before signing a deal at Elland Road.
However, the former France youth international does have some connection with Leeds, having grown up with new midfield teammate Toumani Diagouraga in a Paris suburb.
He explained to the club's official website that this shared history with Diagouraga, who is seven years older than Sacko and joined the Whites in January, is making it easier to settle into life in England.
When asked how he was fitting in with his new teammates, Sacko replied: "Really, really well. I’ve been lucky to be with Toumani Diagouraga - we grew up in the same building in the suburbs of Paris. I was on the second floor of the building and he was on the fourth floor until Toums left to go to Watford.
"He used to come back quite often so we saw each other quite a lot even when he was playing in England. I grew up with Toums, so that made it easier for me here.
"I also know Sol Bamba really well because we have the same agent. We also saw each other during our holidays."
Sacko already looks to be adapting to life at Leeds, judging by his lively goalscoring performance on Wednesday night, and Leeds fans will be hoping that his friendship with Diagouraga can see the pair strike up a profitable combination on the pitch this season.
