Gabriel Martinelli believes there is much more room to improvement for Arsenal.
The Gunners ran out 2-0 winners over Everton in Baltimore on Sunday.
Speaking to the club's website, Martinelli said: "Yeah, we are improving, but there's a big gap of improvement still to happen, but we will try to get there and try to win all the games.
"It was a hard game. We knew that they have a really good team, they are preparing the team as well for the Premier League and we tried to do our best and I think we deserved the win."
Mikel Arteta's side will play Chelsea in Orlando on Wednesday.
Asked about the match, Martinelli added: "Yeah, I'm very excited to go there and do our best as we have done here and try to win all the games there as well."
