The club will now turn their attention to the third round of the Carabao Cup against Port Vale. Mikel Arteta’s side will be at Vale Park on Wednesday, and there are expected to be wholesale changes. Piero Hincapie is another candidate for a maiden start, but the Ecuador international is a doubt for the game. Wednesday’s game against Port Vale should be an easy challenge for the Gunners, but they must be wary of complacency after Grimsby Town’s surprise penalty shoot-out win over Manchester United. Martinelli could lead the line against Port Vale with Viktor Gyokeres and Mikel Merino being rested.
