It's hard to avoid the parallels between Marcus Rashford's Manchester United breakthrough and the opportunity that suddenly presents itself to Amad Diallo.
Back in 2016, 18-year-old Rashford was thrust into United's side for a Europa League tie with Midtjylland when Anthony Martial damaged his hamstring in the warm-up.
Amid a striker injury crisis, Louis van Gaal turned to Rashford - so unknown his name wasn't on the match programme squad lists - and the teenager seized his chance with two goals on the night.
Three days later, with Martial and Wayne Rooney out, Van Gaal started Rashford in the Premier League against a title-chasing Arsenal team.
