Aaron Ramsey is ruled out of Arsenal's match with Borussia Dortmund

Aaron Ramsey will not travel to Germany for Arsenal's Champions League opening group fixture against Borussia Dortmund tomorrow because of an ankle injury.

The Wales captain picked up the problem during training earlier this morning and manager Arsene Wenger confirmed to a press conference a short while ago that Ramsey will remain in London for treatment.

The 20-year-old has started all of the Gunners' Premier League matches so far this season.
