Arsenal boss Mikel Arteta admits Eddie Nketiah may not start at Manchester United tomorrow.

Nketiah struck twice in victory at Chelsea.

Arteta said: "We will see. Let's see how he recovers, how everybody is, and we will try to put the best possible team out to try to win the game.

"It's what he does all the time, he hasn't had enough minutes this season to show what he can do and that's why I said what I said."

On keeping the winning XI, he added: "It is hard, but fortunately that's been the case in many weeks when had to pick others that have to step in and they've done well for the team because they always prepare well.

"That's what we expect, that doesn't mean we are always going to repeat the same line up. We have options to change and we have options to change again tomorrow and play in different ways."
