Manchester United boss Erik ten Hag is delighted with their form facing Arsenal on Sunday.
United have won their last three games.
Ten Hag said: "I have seen some good stuff.
"It's more than details but I see structures are coming. We are constructing and that's good to see. But we have to do that and improve from game to game.
"That is work on the training ground, that is work on the video and that is work in the games. "It's about formation, about getting and creating lines and then making the right decisions.
"But also the decisions on the ball and out of possession, we are making good steps, we have a base but there's still a lot of room for improvement."
