There were flashes of the Gabriel Martinelli from seasons past in the second half against Liverpool on Sunday.
After switching positions with Leandro Trossard to go from the left wing to a false nine, the Brazilian came alive, seizing the central role with intent and urgency.
His sharp movement and hunger to pierce the opposition backline with runs off the ball gave Virgil van Dijk and Co a new problem.
Just two minutes after the interval, Martinelli halved the deficit, heading in Trossard’s cross to kickstart the Gunners’ fightback to a hard-earned point.
