United had 10 Premier League home draws this season (with a hot Palace team to come at the end of the season).
The teams they drew at home:
Stoke, Burnley, Arsenal, West Ham, Liverpool, Hull, Bournemouth, West Brom, Everton, Swansea.
That's home draws against teams currently ranked, 18, 17, 15, 14, 13, 12 and 10 in the league. In the games against elite defensive juggernauts like Burnley and Hull they failed to score at home.
Yes, United 100% bottled it. Against Swansea they allowed an 80th minute equalizer, against Everton they needed a last second penalty to save a point, against WBA they had 3 shots on target, against Bournemouth they were playing against 10 men for the entire 2nd half and couldn't score.
United have the 3rd best away record in the league, only 1 point behind City with two fewer away games played. It's entirely possible they finish the season with the 2nd best away record in the league but miss the top 4 because their home record is currently the 7th best. Manchester United will finish this season winning between 35 and 40% of their home games. That's mindbogglingly terrible.
