Patrick Dorgu and Ayden Heaven were presented to the Manchester United fans ahead of Sunday's Premier League clash against Crystal Palace, with their shirt numbers being revealed.
Heaven's arrival from Arsenal was confirmed on Saturday, and the highly-rated centre-back will wear the number 26 shirt for his new club, while Dorgu, who officially joined on Sunday morning, has been handed the '13' jersey.
Dorgu had the number 13 shirt at Lecce, and he has carried it over to Man United, becoming the first Red Devils player to sport that jersey since Lee Grant during the 2021-22 season.
Heaven, meanwhile, has become the first Man United player to wear the number 26 since Dean Henderson in 2023-24.
The duo were presented to the Old Trafford crowd ahead of Man United's contest with Palace on Sunday, and the pair could potentially be involved against Leicester City in the fourth round of the FA Cup on Friday night.
Dorgu is set to challenge for the starting role as the left-sided wing-back, while Heaven has boosted Man United's centre-back options, with the former Arsenal star also expected to battle for first-team action in the coming weeks.
