Injury could stop Rooney
Josh Harrop, Matthew Willock, 20, Zachary Dearnley, 18, and Angel Gomes, 16, hope to make their debuts at some stage. Mourinho has spent the week assessing which youngsters are ready to take the plunge as he prepares to rest all of his starters for the final except Paul Pogba, who has missed the last two games following the death of his father.
Juan Mata and Anthony Martial may be included to add some first-team knowhow, with Ashley Young also in contention after injury. But the starting line-up is expected to be the youngest in the Premier League this season. Tottenham’s side who faced Stoke in September was the youngest with an average age of 25 years, 47 days.
Mourinho has said Wayne Rooney is an injury doubt that may prevent him from saying what may be his farewell to Old Trafford, while Marouane Fellaini is fighting to recover from a hamstring problem to face Ajax.
