Unai Emery has brought a 21-man squad to Spain for our the second leg of our Europa League semi-final.
We lead 3-1 from the first game at Emirates Stadium last week, thanks to a brace from Alex Lacazette and an injury-time Pierre-Emerick Aubameyang strike.
Our travelling group is above, and an 18-man matchday squad will be named 75 minutes before kick off on Thursday night.
