Premier League champions Manchester United visit the Emirates tomorrow night for a crunch clash with title-chasing Arsenal, with both sides desperate for three precious points in search of very different objectives.
Arsenal are still reeling from Saturday's 5-1 humiliation at the hands of Liverpool but have little time to dwell on that defeat, needing nothing less than victory over United for the first time since 2011 to keep their hopes of keeping pace with Chelsea and Manchester City alive.
United meanwhile could instantly make Sunday's shock 2-2 draw with Fulham at the back of fans minds by beating the Gunners, as Robin van Persie bids to score against his former side for the fourth successive match.
Both squads are packed full of star players but how has United's indifferent campaign affected a select XI comprising the traditional title rivals?
Click ahead to see if we prefer Mesut Ozil or Juan Mata, with this season's form the primary factor in making contentious calls.
