London - Louis van Gaal's increasingly confident Manchester United will look to twist the knife in Manchester City's side when the derby rivals clash in Sunday's Premier League showdown at Old Trafford.
A run of five consecutive victories has taken United above City for the first time this season and another success this weekend would blacken yet further the storm clouds gathering over the Etihad Stadium.
City's 2-1 loss at Crystal Palace on Monday left them nine points behind leaders Chelsea having played a game more, effectively ending their title defence, and they now face a battle to secure a Champions League place.
