Lukaku was set to return to Chelsea, only for Jose Mourinho to swoop in and secure a £75million deal.
For many years, Pogba has been close friends with the 24-year-old and has lifted the lid on his role in convincing him to sign for the Red Devils.
“I had been preparing for this – it was long work,” Pogba said on Copa 90’s FIFA and Chill show.
“I took him to dinner and I talked to him [about Manchester United].
“I had to work for it but the finale is that he’s here, he’s here with us and he’s banging in the goals.
“He’s a player who knows the Premier League well and can help us a lot.”
