For sure - you see this all the time at big clubs where a successful manager moves on. Slot is bucking the trend at Liverpool but more often than not it takes someone to be a fall guy before they move on. Emery is clearly a brilliant manager but had a disaster following Wenger at Arsenal.
LW wasnt here long, but the impact he had at a club starved at success was massive. He was always going to be a difficult act to follow.
