Arsenal defender Ben White has been ruled out for "months" after having knee surgery, manager Mikel Arteta has confirmed.
The Gunners boss says White, 27, has been carrying a number of knocks and a decision was made over the international break for him to have an operation.
"It has been different kinds of struggles. It has never been the same thing, but we had to make a decision. He has not improved over the last few weeks, unfortunately," said Arteta, whose side host Nottingham Forest on Saturday.
"We know that Ben is going to push every boundary, but it got to the point where we have to protect the player and we decided to do the surgery.
