New signing Alexis Sanchez made his first appearance in Arsenal’s colours on Saturday but French striker Yaya Sanogo stole the limelight with a four-goal blast in a 5-1 victory over Benfica in the pre-season Emirates Cup.
Chile forward Sanchez, signed for around 35 million pounds ($58.86 million) from Barcelona last month, came on as a late substitute but by then Sanogo and Costa Rica striker Joel Campbell had done the damage.
The 21-year-old Sanogo has yet to start a Premier League game since joining from Auxerre in July 2013 while Campbell has spent his entire Arsenal career on loan at Lorient, Real Betis and Olympiakos Piraeus.
