Manchester United veteran Ryan Giggs says they cannot afford to lose at Manchester City on Sunday.
United lost both matches last term, including a 6-1 hammering at Old Trafford before losing 1-0 at City, which many feel kick-started their charge to the title.
And Giggs admits those two loses proved crucial, telling Sky Sports: "If we had drawn the game [at City] we would have won the league.
"Those two games were probably the difference so hopefully we can get the result and that will be the difference at the end of the season."
