Arsene Wenger has revealed the latest team news ahead of Wednesday's Champions League clash against Borussia Dortmund:

on Jack Wilshere...As you know he has not travelled because he has not practised. I will know more on Thursday when he has another test. If that is not a success he will definitely be out for Sunday, if he is out for Sunday he will be out for England as well.

on other team news...Gnabry has travelled and is in the squad. Walcott is not far, he should be back soon after the break and Flamini has a good chance to be available on Sunday. Gibbs has travelled and should be available. Eisfield, he was with us this morning in training.
