Manchester United reserves coach Warren Joyce is eager for his loan players to maintain their discipline.
Robbie Brady (Hull City) and Oliver Norwood (Scunthorpe United) have both been sent off in recent weeks.
"Both sendings off look harsh really but things like that are another lesson for them to learn when they go out on loan," Joyce told ManUtd.com. "Things like that can happen.
"You find yourself out of the team with a three-match ban and, in the real world out there, it's not always easy to get back into the team. So that's another thing that teaches them a lesson."
