Ryan Giggs believes Manchester United bright young things will learn lessons after they suffered their first defeat on tour.
It was United's first defeat on the tour after they had beaten both Celtic and Philadelphia Union. Apart from Paul Scholes, Giggs, Dimitar Berbatov and the fit-again Nani, United manager Sir Alex Ferguson fielded an inexperienced team - and it showed at times.
Giggs said: "You learn something from every game you play when you are younger and you always try to take something from it even when you lose. Hopefully the young lads will be better for the experience."
Kansas City Wizards, fifth in Major Soccer League's Eastern Conference, were still savouring a surprise victory over Ferguson's side.
Kei Kamara scored the winner in front of 52,424 fans at the Arrowhead Stadium - a record soccer attendance in mid-America.
Dimitar Berbatov pulled United level only a minute earlier from the penalty spot after Davvy Arnaud had opened the scoring in the 11th minute.
Despite Jimmy Conrad being sent off for his challenge on the Bulgarian, the Wizards stayed resilient and achieved a notable victory.
Giggs added: "The big thing about pre-season is getting your fitness right but of course you want to play well and win your games. It might be a friendly but it's always disappointing when you lose.
"We didn't play well and the second goal was a killer after coming so quickly after we'd got ourselves back into the game and they went down to 10 men. We didn't recover from that.
"It was a good run-out for us. It's hard work in the heat especially when you're a goal down chasing the game but credit to the Wizards, they played well. It's always an experience when you're playing at a great stadium, in front of a good crowd against good opposition. "
