Arsenal made an ideal start to his pre-season campaign with a 3-0 win over the Colorado Rapids.
The gunners played a young side and did not use the big caliber until late.
But they barely had to leave the second report, with a comfortable victory and impressive individual performances.
Bukayo Saka, James Olayinka and newborn Gabriel Martinelli all scored on the match sheet of Unai Emery's men.
Mesut Ozil, Pierre-Emerick Aubameyang and Alexandre Lacazette all had cameos late with the game already won.
Here are five things we learned from their first pre-season game in the United States.
Calum Chambers has a future in Arsenal
He wore the armband that might indicate what Unai Emery thought.
Certainly, with Arsenal's defensive issues and after Chambers' impressive season on loan to Fulham, he has a future at Arsenal.
It is really worth going there. Strong, reliable, good character. What does not love?
Gabriel Martinelli is a perspective
In the midst of all the relentlessness provoked by Arsenal transfers – or lack thereof -, the 18-year-old Brazilian has encouraging prospects and a potential of 6 million pounds.
Martinelli started brilliantly on the right in what often looked like a 4-4-2 but was tenacious, busy and strong. He was rewarded for his lively display with a goal in the 60th minute.
Arsenal fans have such a passion
The Dick Sporting Goods Park has a capacity of 18,000 spectators, a large number of Arsenal fans and many of them came from England with familiar slogans: "Ooh to be a Gooner".
This group will fight for his club, will be heard and his request that the owner shows that he cares did not go unnoticed or ignored by the hierarchy.
The children are well
It was a very young team with seven teenagers in the starter training and yet they looked physically strong, well disciplined and tactically well drilled.
They are not overwhelmed by more experienced opponents and at this time Arsenal has limited funds, it would be fantastic to see a new generation give something to encourage fans.
There has not been a wave of children since George Graham went through Rocastle, Keown, Adams, Hayes and Thomas in the 1980s.
Arsenal needs a similar success rate now.
Eddie Nketiah should not be loaned
There was talk of a 20-year loan and he almost joined Augsburg in January to play games. No doubt about it, he was frustrated at not being allowed out.
But there is a reason behind Unai Emery's decision: Nketiah is clearly making enough progress to stay and be part of the first team at Arsenal.
He grew in stature and confidence, is an excellent finisher with a good touch. No wonder Bristol City takes it, but is it the right choice?
Yes, he can fight against Alexandre Lacazette and Pierre-Emerick Aubamyeng, but it seems that Arsenal is looking for a wingman rather than a center-forward, as Nketiah is coming.
