Arsenal boss Mikel Arteta admits they're yet to secure a work permit for new signing Takehiro Tomiyasu.

Tomiyasu joined from Bologna on deadline day.

His involvement against Norwich remains in doubt, however, as he awaits the relevant documentation.

"We need the work permit first," said Arteta.

"The club is trying hard to achieve that. He is back in the country, I will meet him for the first time today probably and train with him, see how he is, get a feel for it.

"He has been playing, so he should be completely fit. We have been impressed, that is the reason why we decided to sign him.

"Tomi has got the capacity to play in any position in the back four. He has done it all across the back four and in a back three as well. He gives us that versatility.

"He gives different qualities in that right-back position and he is a player that we followed for a long time. He brings qualities that we didn't have in the squad."
