Viktor Gyokeres made his Arsenal debut in Sunday's win at Manchester United with Mikel Arteta identifying an area of the striker's game that they need to work on

Viktor Gyokeres started for Arsenal for his Premier League debut before being substituted around the hour mark for Kai Havertz. Ex-Newcastle boss Alan Pardew has given his verdict on what he called a "poor" performance from the Swedish striker.

Manchester United legend Roy Keane suggested Gyokeres will need some time to get up to speed in the Premier League, particularly as he joined pre-season with Arsenal late after his arrival from Sporting and because of his muscular phrame.
