Arsenal boss Mikel Arteta has challenged Fabio Vieira to do more in training.
Arteta was asked about Vieira's absence in recent games.
He said: "If they train really well and play really well, I guarantee they'll have the minutes they need.
"The other boys have had more minutes, but to develop yourself sometimes you need a different position, a different environment.
"That's what we need to know..."
