Arsenal boss Mikel Arteta praised Fabio Vieira and Gabriel Jesus for their Europa League victory over Bodo/Glimt.
Vieira struck in the 3-0 win on Thrusday night.
Arteta said of Vieira: "Yes, you saw the quality. Every time he's around the box he's a real threat, really intelligent player and brave. In defending he still needs to do more and understand it more because organisation is key when you play against good teams in ball possession."
On Gabriel Jesus' impact off the bench, the manager also said: "I love his mentality. It doesn't matter how long he players, when he plays, in which position. He always gives absolutely everything. You see his pressing when he goes on the pitch, it makes the team different. His energy as well.
"Obviously today he (made) an outstanding action, to create the third goal."
