That's 15 managers in about 16 years.
Emery was 2008 to 2012 mate
Looking at that list he was actually their longest serving manager in the last 15 years (including 15 managers), 4 years and left for another job - wasn't sacked, only Benetez came close to that tenure at 3 years, pretty impressive feat actually
