Arsenal boss Mikel Arteta was happy with Jurrien Timber in defeat to Manchester United in New Jersey.
United won the preseason friendly 2-0, though Timber impressed on the day.
Arteta said: “With Jurrien, we are really pleased with his performance and the things we asked him to do.
“Obviously he is adapting really quickly to the team, and you could see the confidence, the determination that he plays with.”
On the midfield trio of Kai Havertz, Declan Rice and Martin Odegaard, the manager also said: “When they play 55 times together they will be better. It will flow better, they will understand each other better and will be more dominant and better. But it takes time to glide and we have to respect that.
“But I saw a lot of positive things, and things I like much more than the game we won the other day against the MLS even though the result is very different.”
