Former Manchester United captain Roy Keane has a challenge for youngster Alejandro Garnacho.
The winger has been impressive for the first team this season, getting chances under coach Erik ten Hag.
Garnacho started the second leg of the Carabao Cup semi final against Nottingham Forest, which United won 2-0 on the night and 5-0 on aggregate.
"Every player is so different," Keane told Sky Sports ahead of the game.
"The fact he's so young and he's had more of an impact coming off the bench, so he'll be delighted to get his opportunity [starting vs Forest].
"If you want to be an attacking, young player for Man United, you've got to be brave, you've got to have courage, you've got to affect games when you get your opportunity, which is what we saw with this great finish late in the game [against Fulham in November]. As a young player he'll have to get more consistent.
"But listen, he's fantastic, and he's getting involved. That's what you want from any attacking player when he starts - he's getting assists, a few goals, he played a huge part in United's season [against Manchester City] - we talk about momentum turns - you wouldn't want to play against him, and he's exciting to watch. That's what United fans want to see."
