Manchester United and Liverpool are the two most successful clubs in English football, but last season they couldn't have been much further apart.
Liverpool won the Premier League title at a canter, while United recorded their worst finish since the 1973-74 season, when they were relegated from the First Division.
It is still too early to judge where either side is at this campaign, though Liverpool head into this weekend's derby clash sitting 2nd in the table, five points ahead of United, who are in 10th.
The mood of both fanbases could be altered by the result this weekend, and ahead of the match, we looked at whether any of United's current stars would get into a combined starting line up with the Liverpool squad. Here is what it could look like in a 4-3-3 formation.
