Mauricio Pochettino begins a new challenge next season at Tottenham, hand picked as the new Tottenham head coach earlier this week.
Moyes' tenure did not even last a year, and was about as ill-fated as they come, United dropping from 1st a year ago to 7th, behind a stagnated Tottenham side - and his own reputation in tatters.
At least he has his record at Everton to fall back on when it comes to his own personal achievement, but he somewhat tarnished his reputation among fans where he spent a decade with his decisions at United last summer.
Moyes persisted in attempting to sign Everton players, particularly Leighton Baines, landing up signing Marouane Fellaini.
While also linked with Seamus Coleman, the a £30 million double bid for Baines and Fellaini angered Everton last summer, seen as disrespectful by Moyes and United, a ludicrous sum considering they landed up paying £27.5 million for Fellaini alone on deadline day.
When Moyes returned to Goodison Park with United last month, a match which preceded his sacking, he was made to feel unwelcome.
Moyes was booed as he arrived at the stadium and during the game, with chants of 'You're Getting Sacked in the Morning' ringing round the ground.
There was an argument fans should have been more respectful considering his long tenure with Everton, but they were clear in their reasoning.
This is a lesson Mauricio Pochettino has an option to take heed of or ignore as he prepares to spend a reported £50 million transfer budget this summer.
Southampton fans are already worrying about their top stars being sold, with Liverpool and Manchester United strongly linked, the last thing needed is their former manager to get in on the act.
Pochettino has even less of a legacy at Southampton than Moyes did at Everton, it's up to him whether he wants to preserve it or risk it becoming tarnished among fans who held him in very high regard.
