Manchester United boss Jose Mourinho says it was "important" for his team to lose the friendly game against Barcelona.
The Red Devils suffered a 1-0 defeat against the Spanish giants but the Portuguese was still satisfied.
"It's very important to lose a match in pre-season," he said after the game.
"You don't like to lose but I think it's very important. I think it would be very bad for us to leave the US without a defeat, playing against teams like Real Madrid, Barcelona, Manchester City, it would be very bad to go home with just victories.
"So the defeat is good. But I think in the game we did some very good things and we did bad things. The very good things are to keep and the bad things are to improve."
Asked about the level of Paul Pogba, he added: "With Messi and Neymar, there is only one [of each].
"There are not two. Suarez, Iniesta, Pique, Ronaldo, Bale, Modric, Toni Kroos, there is only one of them. So they can only play for one club and not two.
"We cannot have them. They belong to the clubs. You can be working very hard tactically to improve your team, to improve your players, but some players are special and against that nature there is nothing you can do.
"In the real matches you try to compensate the difference in quality with a certain tactical organisation, and with that you can win. In football it is possible for a team to be better than the sum of the parts. But the parts are amazing. Their relationship with the ball is amazing.
"You can argue about the occupation of space, tactics and compact blocks, but the player's relationship with the ball is still the most important thing. Even as an opponent on the bench like I am, it is beautiful to see the guys' relationship with the ball.
"Today, one of my players, Paul Pogba, showed the level. He showed that he belongs at that level."
