They must be after the Guinness Book of Records for the number of different managers in a season. Mind you, they probably already hold it!
17 in the past ten years It is hard to untangle them date wise, but they do seem to like three a season more recently.
They're looking for their 15th permanent manager since 2012/13. Only three fewer than West Ham have had in their entire history.
Had a look at ex hammers managers Very sad the first one killed himself when he got the sack After thirty years as manager.
