We're not sure what was more painful at Stamford Bridge on Wednesday night—John Obi Mikel's performance or when Mohamed Diame stacked it into the Matthew Harding Lower, flying over the advertising screens and into the onlooking fans.
Both were equally unnerving, although we're pretty sure what was more concerning for Chelsea supporters.
Mikel didn't have much to do defensively on account of what Mourinho called Sam Allardyce's "19th century football" in a press conference after the match, but it still meant he was pretty worthless in attack for the Blues.
With the Hammers camped in their own half for much of the game, Chelsea needed to move the ball at pace, unsettle the defenders and pull players out of position.
Instead, whenever Mikel was in possession, time seemed to stop. The Nigerian was far too relaxed, playing with little energy and desire to break West Ham down. And when he did find a teammate, it was often the wrong player at the wrong time.
It's not a game in isolation, though. The 26-year-old has been that way since joining from Lyn Oslo in 2006.
Quite what Chelsea and Manchester United got in a squabble over when competing for his signature back then, we'll never know.
A similar bidding war now would do Chelsea a massive favor.
