Not so long ago, Manchester United and Arsenal was the go-to game in the Premier League, with both going for the title and Sir Alex Ferguson and Arsene Wenger sworn enemies.
In recent years, with the decline of both teams, games between them have lost their intensity, but Sunday at Old Trafford could be a throwback to those epic battles of the past.
Arsenal go to Old Trafford top of the table, with the only 100 per cent record in the Premier League, while United will be looking to continue their revival by making it four wins in a row.
