Arsenal boss Mikel Arteta insists he's happy with the progress of Fabio Vieira.
The summer signing from Porto has struggled for regular minutes since his arrival.
But Arteta says: "Fbio Vieira? He's starting to give me a lot of headaches because I see what he's capable of every day.
"Now he understands exactly what we want and physically he's in a position to compete at the right level.
"I'm really looking forward to giving him more minutes."
