Premier League protagonists Manchester City and Arsenal are set to square off in the pick of the FA Cup fourth-round fixtures.
Arsenal sit five points above City with a game in hand in the Premier League, but they travel to Manchester on Friday night having lost six games on the bounce at the Etihad Stadium.
The two sides are yet to meet this season, with their initial October date pushed back due to Arsenal's Europa League commitments. Friday's encounter is now the first of three intriguing clashes to come.
