Unai Emery believes attack will be the best form of defence for Arsenal when they head to Valencia looking to secure a place in the Europa League final.
The Gunners travel to Spain next week for the second leg of their semi-final clash having won 3-1 at the Emirates Stadium in Thursday's opening leg.
Alexandre Lacazette netted a first-half brace to cancel out Mouctar Diakhaby's deserved early opener for the visitors, with Pierre-Emerick Aubameyang adding a third in the final minute.
