Help pick our Manchester United-Chelsea combined XI ahead of the champions' trip to Old Trafford on Nissan Super Sunday.
Throughout the week we'll be asking you to select a goalkeeper, a defence, a midfield and an attack of the combined XI, which will adopt a 4-2-3-1 formation.
Today it's time to select a defence - a right-back, two centre-backs and a left-back. So will you go for Azpilicueta or Valencia, Jones or Cahill, Rojo or Rudiger or Young or Alonso?
Use the 'upvote' button for your favourites in the interactive tools below, and remember to keep across the Sky Sports platforms on Friday as we reveal YOUR Manchester United-Chelsea XI ahead of their clash at Old Trafford.
Watch Man Utd v Chelsea on Nissan Super Sunday from 1pm on Sky Sports Premier League.
