Viktor Gyokeres finally opened his Arsenal account in their final pre-season fixture of the summer.
The Gunners completed the £63.7million signing of the striker from Sporting Lisbon towards the end of July - ending an agonisingly long wait for supporters to sign an out-and-out No.9.
Gyokeres made his debut for club in their 1-0 defeat to north London rivals Tottenham in Hong Kong.
He also failed to net against Villarreal during the week, but made it third time lucky on Saturday with the visit of Athletic Bilbao.
The 27-year-old netted the opener in their Emirates Cup clash with a thumping header from fellow summer signing Martin Zubimendi's cross.
Gyokeres scored just five times with his head for Sporting across 102 appearances in Portugal - leading to jibes from rival supporters
