United finished the season in sixth and only qualified for the Europa League because West Ham were beaten 3-1 by Brighton. A Hammers victory would have seen them leapfrog the Old Trafford outfit.
Interim boss Ralf Rangnick guided United to their lowest Premier League points tally of 58. The loss at Palace was their twelfth of a desperately disappointing campaign.
Ten Hag has a significant job on his hands as he attempts to rebuild the club. There is predicted to be a monumental overhaul of the United squad this summer – with several departures.
Paul Pogba and Jesse Lingard will likely be just two who exit Old Trafford – with the pair leaving when their contracts expire at the top of June. United have been linked with a few big-name signings, but face strong competition from some clubs who could offer a more attractive destination in the event that they are within the Champions League next term.
