"Development is the key at clubs like Manchester United," Joyce continued. "We've got to win and win the right way as well.
"Pressure situations on nights like these do help the development and we need more types of games where you're playing under scrutiny from crowds when, if you make small mistakes, it can cost you big time. They need to know that and we ram it into them every day.
"They have got to be perfect in everything – even the little passing drills. We're hoping that sinks in and stands them in good stead for the rest of their careers. The more crosses against them and things that are wrong, the lower down they are going to end up."
