The final game of their campaign came at home to already relegated Cardiff City, who came to Old Trafford with just pride to play for and left the stadium with a 2-0 win and the scalp of a once great English club.
Ole Gunnar Solskjaer has warned his Manchester United squad to be fit before they report back for pre-season this summer or risk being excluded from the club's summer tour. Our live coverage lets you follow all the key moments as they happen.

United had been challenging for third place as recently as the March global break only for the catastrophic loss of form, that directly followed Solskjaer's appointment on a permanent basis, to cost them - and that despite the indifferent showings of their rivals for a top-four finish.
Each player has been given an individual fitness and nutrition plan for the summer to keep them in top shape in the off-season and Solskjaer has insisted that if the plans are not adhered to, players will be dropped from pre-season. If we can get the momentum early on, I'm sure we can catch a few teams. We know what we have to work on, the player have got the message quite clearly as well.
However, the wheels have since fallen off again and United's form guide in the latter part of the season makes for ugly viewing. Greenwood replaces the injured Alexis Sanchez, while Jesse Lingard comes into the side in place of Juan Mata.
"Of course we're used to challenging for the Premier League and that's not going to be sorted quickly", he said.
We are sixth and that's not where Manchester United want to be.
