United were the more impressive side for much of the game, but that did not stop a resurgent, if tepid, Chelsea from using their experience and determination to dominate for large stretches, especially in the second half.
When United got their goal, an excellently worked move finished by Jesse Lingard, the away side shrunk back and invited pressure, despite having seen that Chelsea were there for the taking. Once again, it was an ultimately conservative and cowardly performance when another way was obviously the most successful.
Memphis was slightly unfortunate that his terrible pass resulted in the equaliser, and Daley Blind's lack of composure compounded the situation when he rushed out to intercept a pass instead of keeping a tight line, but Memphis should really have tracked back. There's no suggestion that he isn't really a hard worker, but it's the kind of thing which will make fans cut their losses with him. He may only have the rest of the season to save his career, and he might consider keeping his head down for the next couple of months. There's talent there, it just needs to be properly used.
