That's more like the Arsenal we all want to see, thoroughly professional against inferior opposition, just shows how poor we were in the 1st leg.
I certainly don't want to see David Luiz and Willian start another Arsenal match, unless it's due to injuries/desperation.
We're definitely better without Aubameyang for now and him having Malaria may mean we won't see him for the rest of the season anyway.
Onwards and upwards!
