Newspaper reports have claimed that the 18-year-old United star chose the budget chicken restaurant for his date while dressed in a tracksuit and trainers.
Following the story, Nando's have decided to poke fun at the teenager, who is said to be earning £30,000 per week, by offering him a £50 voucher.
The Nando's official Twitter account posted a photo of the voucher, along with the message: "Hey Adnan, the second date's on us. (P.S. Maybe ditch the trackies?)"
