The young Reds are aiming to build on the 4-3 win against Bayer Leverkusen in the opening Group A fixture and have a fully-fit squad in Ukraine, with the exception of Louis Rowley, who is a doubt.
"Obviously, it's the first away trip and the last game we played was a great result, first of all, but a good education for the lads as well," Butt told ManUtd.com at the team hotel in Donetsk.
"The way Bayer played was totally different to what they are used to week in and week out in the leagues they play in. Now they will play in a different environment, with a different way of travelling and with the press all around, although obviously focusing on the first team. When they see that at the airport, if they are going to be first-team players, they have to deal with all this - coming to different countries and doing different tactical work. It's invaluable for them."
Ben Pearson has recovered from an ankle injury but there is a question mark over defender Rowley's involvement.
"Ben's okay," confirmed Butt. "I've got a fully-fit squad but I think Louis is struggling a little bit with his shoulder. Other than that, I've got a full squad and I'm excited about today. It's going to be a great game in a great stadium and, hopefully, we'll get a good crowd.
"It’s a great trip and a great game to play in before going to watch the first team. It’s invaluable for the lads. You couldn’t buy the experience they are getting."
