For Unai Emery this was an occasion to both savour his work and question himself. The
Arsenal manager quite rightly took great delight in seeing his team maintain a perfect start to their Europa League campaign in rampant
fashion but it hardly did his reputation as a judge of players much good that the man who got two of Arsenal’s four goals against Standard Liège is someone Emery does not feel has what it takes to be a striker.
That was Emery’s assertion of Gabriel Martinelli before this game yet he will now have to have a rethink. The 18-year-old, who arrived from the Brazilian side Ituano in the summer, scored two goals of high-quality, adding to the two he got against Nottingham Forest in the Carabao Cup last month, and throughout looked a real threat from a centre-forward position. If he cannot make it as a goalscorer then it is hard to see who can.
