Although Man Utd would love to challenge for the 4th spot, they run a risk of spoiling their next season if they end up in Europa League.
On current form, I don't see them going past 5th, and most likely they should end up 6th. They would be praying for City to lose.
Teams in EL get stuck in EL, because they can't progress in the league.
Oofcourse, I'm being overly critical of EL, but the truth is, it's not competition you would love to be in.
