Arsenal boss Mikel Arteta insists there's no questioning Hector Bellerin's commitment.

It's been suggested Bellerin has been offered back to former club Barcelona.

But Arteta says, "As you said he's had a lot of injuries in the past season that hasn't allowed him to be very consistent, even in training or in the games that he's played. And obviously when that happens your level of consistency in performance will always drop.

"But the effort that he puts in, the commitment that he shows to the club and the players is always at the top. And his performances can improve, of course they can, and he's trying hard to do that. We are here to help him."
